Description

Clock Source Select Control Register 1

Fields

WDT_S	Watchdog Timer clock source select. These bits are protected bit, program this need a open lock sequence, write “59h”,“16h”,“88h” to address 0x5000_0100 to un-lock this bit. Reference the register REGWRPROT at address GCR_BA + 0x100 00 = clock source from external crystal clock (4 ~ 24MHz). 10 = clock source from HCLK/2048 clock 11 = clock source from internal 10KHz oscillator clock
ADC_S	ADC clock source select. 00 = clock source from external crystal clock (4 ~ 24MHz). 01 = clock source from PLL clock 1x = clock source from internal 22.1184 MHz oscillator clock
TMR0_S	TIMER0 clock source select. 000 = clock source from external crystal clock (4 ~ 24MHz) 010 = clock source from HCLK 011 = clock source from external trigger 1xx = clock source from internal 22.1184 MHz oscillator clock
TMR1_S	TIMER1 clock source select. 000 = clock source from external crystal clock (4 ~ 24MHz) 010 = clock source from HCLK 011 = clock source from external trigger 1xx = clock source from internal 22.1184 MHz oscillator clock
TMR2_S	TIMER2 clock source select. 000 = clock source from external crystal clock (4 ~ 24MHz) 010 = clock source from HCLK 011 = clock source from external trigger 1xx = clock source from internal 22.1184 MHz oscillator clock
TMR3_S	TIMER3 clock source select. 000 = clock source from external crystal clock (4 ~ 24MHz) 010 = clock source from HCLK 011 = clock source from external trigger 1xx = clock source from internal 22.1184 MHz oscillator clock
UART_S	UART clock source select. 00 = clock source from external crystal clock (4 ~ 24MHz) 01 = clock source from PLL clock 1x = clock source from internal 22.1184 MHz oscillator clock
PWM01_S	PWM0 and PWM1 clock source select. PWM0 and PWM1 uses the same Engine clock source, both of them with the same pre-scalar 00 = clock source from external crystal clock (4 ~ 24MHz) 10 = clock source from HCLK 11 = clock source from internal 22.1184 MHz oscillator clock
PWM23_S	PWM2 and PWM3 clock source select. PWM2 and PWM3 uses the same Engine clock source, both of them with the same pre-scalar 00 = clock source from external crystal clock (4 ~ 24MHz) 10 = clock source from HCLK 11 = clock source from internal 22.1184 MHz oscillator clock
