Bit 7,6

T0M1, T0M0: Timer0 operation mode selection

00: no mode available

01: event counter mode

10: timer mode

11: pulse width capture mode

Bit 5

T0S: timer clock source

0: fSYS

1: LXT oscillator

T0S selects the clock source for fTP which is provided for Timer 0, the Time-Base and

the PWM. If the PWM is enabled, then fSYS will be selected, overriding the T0S selection.

Bit 4

T0ON: Timer/event counter counting enable

0: disable

1: enable

Bit 3

T0EG:

Event counter active edge selection

0: count on raising edge

1: count on falling edge

Pulse Width Capture active edge selection

0: start counting on falling edge, stop on rasing edge

1: start counting on raising edge, stop on falling edge

Bit 2~0

T0PSC2, T0PSC1, T0PSC0: Timer prescaler rate selection

Timer internal clock=

000: fTP

001: fTP/2

010: fTP/4

011: fTP/8

100: fTP/16

101: fTP/32

110: fTP/64

111: fTP/128
