14.0 TIMERA/B MODULES
TimerA and TimerB are two more Timer0-type
modules. Timers A and B are available as general-
purpose timers/counters, and are closely integrated
with the capacitive sensing modules.
The TimerA/B modules incorporate the following
features:
• 8-bit timer/counter register (TMRx)
• 8-bit prescaler
• Programmable internal or external clock source
• Programmable external clock edge selection
• Interrupt on overflow
• TMRA can be used to gate Timer1
• TMRB can be used to gate Timer3
Figure 14-1 is a block diagram of the TimerA/TimerB
modules.
