Fields

WDT_S	Watchdog Timer clock source select (write-protection bits) These bits are protected bit, program this need to write “59h”, “16h”, “88h” to address 0x5000_0100 to disable register protection. Reference the register REGWRPROT at address GCR_BA+0x100. 00 = Clock source from external 4~24 MHz crystal clock. 01 = Reserved 10 = Clock source from HCLK/2048 clock. 11 = Clock source from internal 10 kHz oscillator clock.
ADC_S	ADC clock source select 00 = Clock source from external 4~24 MHz crystal clock. 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 4~24 MHz crystal clock. 001 = Clock source from external 32.768 kHz crystal clock. 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 4~24 MHz crystal clock. 001 = Clock source from external 32.768 kHz crystal clock. 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 4~24 MHz crystal clock. 001 = Clock source from external 32.768 kHz crystal clock. 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 4~24 MHz crystal clock. 001 = Clock source from external 32.768 kHz crystal clock. 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 4~24 MHz crystal clock. 01 = Clock source from PLL clock. 1x = Clock source from internal 22.1184 MHz oscillator clock.
CAN_S	CAN clock source select 00 = Clock source from external 4~24 MHz crystal clock. 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 use the same prescaler. 00 = Clock source from external 4~24 MHz crystal clock. 01 = Clock source from external 32.768 kHz crystal clock. 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 use the same prescaler. 00 = Clock source from external 4~24 MHz crystal clock. 01 = Clock source from external 32.768 kHz crystal clock. 10 = Clock source from HCLK. 11 = Clock source from internal 22.1184 MHz oscillator clock.
