Table 35. 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, detailed in 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), stores the least-significant
byte (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 36. 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.
