Timer Reload Registers—High Byte
The Timer Reload Register—High Byte, detailed 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.
The Timer Data registers and Timer Reload registers share the same address space.
Table 36. Timer Reload Registers—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, detailed in
grammable 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 follow-
ing the rising edge of the port pin.
