Timer 3 Registers
bit 0: TM3RUN
This bit selects the timer 3 operation mode.
The timer 3 operation mode can be selected as auto-reload mode or 16-bit timer mode.
bit 1, 0: TM3CL1, TM3CL0
These bits select the timer 3 clock.
The timer 3 clock can be selected as TBCCLK (low-speed clock), HSCLK (high-speed clock), external
clock (T13CK: secondary function of PB.3), or the timer 2 overflow flag.
When using as a 16-bit timer, select timer 2 overflow for the clock.
Note:
If HSCLK is used as the clock, after ENOSC (bit 1 of FCON) is set to “1”, wait for the following time interval before
starting timer operation.
•
Wait at least 10 ms when using ceramic oscillation.
•
Wait at least 300
