Bit 7

PCFG: pin-out remapping configuration

0: INT/TC0/PFD pin shared with PA3/PA2/PA1

1: INT/TC0/PFD pin shared with PB5/PB4/PB3

Bit 6

PFDCS: PFD clock source

0: timer0

1: timer1

Bit 5

PWMSEL: PWM type selection

0: 6+2

1: 7+1

Bit 4

PWMC1: I/O or PWM1 control

0: I/O

1: PWM1 output

Bit 3

PWMC0: I/O or PWM0 control

0: I/O

1: PWM0 output

Bit 2

PFDC: I/O or PFD control

0: I/O

1: PFD output

Bit 1

LXTLP: LXT oscillator low power control function

0: LXT oscillator start-up mode

1: LXT oscillator Low Power mode

Bit 0

CLKMOD: system clock mode selection.

0: High speed - HIRC/ERC/HXT used as system clock

1: Low speed - LXT used as system clock, internal HIRC/ERC/HXT stopped.

Note:

If PWM0/1/2 output is selected by PWMC0/1/2 bit, fTP comes always from fSYS.

(fTP is the clock source for timer0/2 , time base and PWM)

Bit 3~0

WDTEN3, WDTEN2, WDTEN1, WDTEN0: WDT function enable

1010: WDT disabled

Other values: WDT enabled - Recommended value is 0101

If the

²watchdog timer enable² is configuration option is selected, then the watchdog timer will

always be enabled and the WDTEN3~WDTEN0 control bits will have no effect.

Note:

The WDT is only disabled when both the WDT configuration option is disabled and when bits

WDTEN3~WDTEN0=1010.

The WDT is enabled when either the WDT configuration option is enabled or when bits

WDTEN3~WDTEN0

¹1010.
