Timer Reload High Byte Registers
The Timer Reload High Byte registers, detailed in
cant byte (MSB) of the 2-byte timer reload value. In CONTINUOUS mode, the
timer reload value is reloaded into the timer upon reaching an end-of-count. When
the RST_EN bit (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.
TMR2_RR_H = 0088h, TMR3_RR_H = 008Bh, TMR4_RR_H = 008Eh)
TMR2_RR_L = 0087h, TMR3_RR_L = 008Ah, TMR4_RR_L = 008Dh)
The timer data registers and timer reload registers share the same
address space.

Description
reload value, {TMRx_RR_H[7:0], TMRx_RR_L[7:0]}. Bit 7
is bit 7 of the 16-bit timer reload value. Bit 0 is bit 0 (lsb) of
the 16-bit timer reload value.
Description
reload value, {TMRx_RR_H[7:0], TMRx_RR_L[7:0]}. Bit 7
is bit 15 (msb) of the 16-bit timer reload value. Bit 0 is bit 8
of the 16-bit timer reload value.
