Table 34. Timer Data Register—High Byte(TMR0_DR_H = 0082h, TMR1_DR_H =
0085h, TMR2_DR_H = 0088h, TMR3_DR_H = 008Bh, TMR4_DR_H = 008Eh, or
TMR5_DR_H = 0091h)
Timer Reload Register—Low Byte
The Timer Reload Register—Low Byte, listed in
(LSB) 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 35. Timer Reload Register—Low Byte(TMR0_RR_L = 0081h, TMR1_RR_L =
0084h, TMR2_RR_L = 0087h, TMR3_RR_L = 008Ah, TMR4_RR_L = 008Dh, or
TMR5_RR_L = 0090h)

TMRx_RR_L
The Timer Data registers and Timer Reload registers share the same address
space.
Value
00h–FFh These bits represent the High byte of the 2-byte timer data
Value
00h–FFh These bits represent the Low byte of the 2-byte timer
Description
value, {TMRx_DR_H[7:0], TMRx_DR_L[7:0]}. Bit 7 is bit 15
(msb) of the 16-bit timer data value. Bit 0 is bit 8 of the 16-bit
timer data value.
