TMRx_DR_H
00h–FFh These bits represent the High byte of the 2-byte timer data
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.
Timer Reload Registers—Low Byte
The Timer Reload Register—Low Byte, described in Table 35, 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.
Note:
The Timer Data registers and Timer Reload registers share the same address space.
Table 35. Timer Reload Registers—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)
