Table 33. Timer Data Registers—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 Registers—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, detailed in
timer 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.
The timer data registers and timer reload registers share the same address space.
Table 34. Timer Data Registers—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)
