Timer Data Register—Low Byte
This Read Only register returns the Low byte of the current count value of the selected
timer. The Timer Data Register—Low Byte, listed in
is in operation. Reading the current count value does not affect timer operation. To read
the 16-bit data of the current count value, {TMRx_DR_H[7:0], TMRx_DR_L[7:0]}, first
read the Timer Data Register—Low Byte and then read the Timer Data Register—High
Byte. The Timer Data Register—High Byte value is latched when a Read of the Timer
Data Register—Low Byte occurs.
Table 33. Timer Data Register—Low Byte(TMR0_DR_L = 0081h, TMR1_DR_L =
0084h, TMR2_DR_L = 0087h, TMR3_DR_L = 008Ah, TMR4_DR_L = 008Dh, or
TMR5_DR_L = 0090h)
Timer Data Register—High Byte
This Read Only register returns the High byte of the current count value of the selected
timer. The Timer Data Register—High Byte, listed in
while the timer is in operation. Reading the current count value does not affect timer oper-
ation.
To read the 16-bit data of the current count value, {TMRx_DR_H[7:0],
TMRx_DR_L[7:0]}, first read the Timer Data Register—Low Byte and then read the
Timer Data Register—High Byte. The Timer Data Register—High Byte value is latched
when a Read of the Timer Data Register—Low Byte occurs.
