Note:
Timer Data Registers—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, 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.

Reserved.
The timer operates in SINGLE PASS mode. PRT_EN (bit 0) is
reset to 0, and counting stops when the end-of-count value is
reached.
The timer operates in CONTINUOUS mode. The timer reload
value is written to the counter when the end-of-count value is
reached.
Clock ÷ 4 is the timer input source.
Clock ÷ 16 is the timer input source.
Clock ÷ 64 is the timer input source.
Clock ÷ 256 is the timer input source.
The reload and restart function is disabled.
The reload and restart function is enabled. When a 1 is written to
RST_EN, the values in the reload registers are loaded into the
downcounter and the timer restarts.
The programmable reload timer is disabled.
The programmable reload timer is enabled.
