Note2: These bits are write protected bit. Refer to the REGWRPROT register.
[5:3] STCLK_S Cortex-M0 SysTick Clock Source Select (Write Protect)
If SYST_CSR[2] = 1, SysTick clock source is from HCLK.
If SYST_CSR[2] = 0, SysTick clock source is defined by STCLK_S(CLKSEL0[5:3]).
000 = Clock source from external 4~24 MHz high speed crystal clock.

CLK_T::PWRCON

Offset: 0x00 System Power-down Control Register

Bits Field Descriptions
[0] XTL12M_EN External 4~24 MHz High Speed Crystal Enable (HXT) Control (Write Protect)
The bit default value is set by flash controller user configuration register CFOSC (Config0[26:24]).
When the default clock source is from external 4~24 MHz high speed crystal, this bit is set to 1 automatically.
0 = External 4~24 MHz high speed crystal oscillator (HXT) Disabled.
1 = External 4~24 MHz high speed crystal oscillator (HXT) Enabled.
Note: This bit is write protected bit. Refer to the REGWRPROT register.
[2] OSC22M_EN Internal 22.1184 MHz High Speed Oscillator (HIRC) Enable Control (Write Protect)
0 = Internal 22.1184 MHz high speed oscillator (HIRC) Disabled.
1 = Internal 22.1184 MHz high speed oscillator (HIRC) Enabled.
Note: This bit is write protected bit. Refer to the REGWRPROT register.
[3] OSC10K_EN Internal 10 KHz Low Speed Oscillator (LIRC) Enable Control (Write Protect)
0 = Internal 10 kHz low speed oscillator (LIRC) Disabled.
1 = Internal 10 kHz low speed oscillator (LIRC) Enabled.
Note: This bit is write protected bit. Refer to the REGWRPROT register.
[4] PD_WU_DLY Wake-up Delay Counter Enable Control (Write Protect)
When the chip wakes up from Power-down mode, the clock control will delay certain clock cycles to wait system clock stable.
The delayed clock cycle is 4096 clock cycles when chip work at external 4~24 MHz high speed crystal, and 256 clock cycles when chip work at internal 22.1184 MHz high speed oscillator.
0 = Clock cycles delay Disabled.
1 = Clock cycles delay Enabled.
Note: This bit is write protected bit. Refer to the REGWRPROT register.
[5] PD_WU_INT_EN Power-Down Mode Wake-Up Interrupt Enable Control (Write Protect)
0 = Power-down mode wake-up interrupt Disabled.
1 = Power-down mode wake-up interrupt Enabled.
Note1: The interrupt will occur when both PD_WU_STS and PD_WU_INT_EN are high.
Note2: This bit is write protected bit. Refer to the REGWRPROT register.
[6] PD_WU_STS Power-down Mode Wake-Up Interrupt Status
Set by "Power-down wake-up event", it indicates that resume from Power-down mode.
The flag is set if the GPIO, USB, UART, WDT, TIMER, I2C or BOD wake-up occurred.
This bit can be cleared to 0 by software writing "1".
Note: This bit is working only if PD_WU_INT_EN (PWRCON[5]) set to 1.
[7] PWR_DOWN_EN System Power-down Enable Bit (Write Protect)
When this bit is set to 1, Power-down mode is enabled and chip Power-down behavior will depends on the PD_WAIT_CPU bit
(a) If the PD_WAIT_CPU is 0, then the chip enters Power-down mode immediately after the PWR_DOWN_EN bit set.
(b) if the PD_WAIT_CPU is 1, then the chip keeps active till the CPU sleep mode is also active and then the chip enters Power-down mode (recommend)
When chip wakes up from Power-down mode, this bit is cleared by hardware.
User needs to set this bit again for next Power-down.
In Power-down mode, 4~24 MHz external high speed crystal oscillator (HXT) and the 22.1184 MHz internal high speed RC oscillator (HIRC) will be disabled in this mode, but the 10 kHz internal low speed RC oscillator (LIRC) is not controlled by Power-down mode.
In Power- down mode, the PLL and system clock are disabled, and ignored the clock source selection. The clocks of peripheral are not controlled by Power-down mode, if the peripheral clock source is from the 10 kHz internal low speed RC oscillator (LIRC).
The clocks of peripheral are not controlled by Power-down mode, if the peripheral clock source is from the internal 10 kHz low speed oscillator.
0 = Chip operating normally or chip in Idle mode because of WFI command.
1 = Chip enters Power-down mode instantly or waits CPU sleep command WFI.
Note: This bit is write protected bit. Refer to the REGWRPROT register.
[8] PD_WAIT_CPU This Bit Control The Power-Down Entry Condition (Write Protect)
0 = Chip enters Power-down mode when the PWR_DOWN_EN bit is set to 1.
1 = Chip enters Power-down mode when the both PD_WAIT_CPU and PWR_DOWN_EN bits are set to 1 and CPU run WFI instruction.
Note: This bit is write protected bit. Refer to the REGWRPROT register.
