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: f_SYS
1: LXT oscillator
T0S selects the clock source for fTP which is provided for Timer 0~2, the Time-
Base and the PWM. If the PWM is enabled, then f_SYS 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 raising edge
1: start counting on raising edge, stop on falling edge
Bit 2~0
T0PSC2, T0PSC1, T0PSC0: Timer prescaler rate selection
