Note:
Timer Reload Register—High Byte
The Timer Reload Register—High Byte, listed in
byte (MSB) of the 2-byte timer reload value. In CONTINUOUS mode, the timer reload
value is reloaded into the timer upon end-of-count. When RST_EN (TMRx_CTL[1]) is set
to 1 to enable the automatic reload and restart function, the timer reload value is written to
the timer on the next rising edge of the clock.
Table 36. Timer Reload Register—High Byte(TMR0_RR_H = 0082h, TMR1_RR_H =
0085h, TMR2_RR_H = 0088h, TMR3_RR_H = 008Bh, TMR4_RR_H = 008Eh, or
TMR5_RR_H = 0091h)
Timer Input Source Select Register
The Timer Input Source Select register, listed in
for Programmable Reload Timer 0–3 (TMR0, TMR1, TMR2, TMR3). Event frequency
must be less than one-half of the system clock frequency. When configured for event
inputs through the port pins, the Timers decrement on the fifth system clock rising edge
following the rising edge of the port pin. The timer event input can arrive from the GPIO
port, the real-time clock, or the system clock. The value of the clock divider in the Timer
Control Register is ignored when the timer event input is either from the GPIO port pin or
the real-time clock source.
