and then read the Timer Data High Byte register. The Timer Data High Byte regis-
ter value is latched when a read of the Timer Data Low Byte register occurs.
Timer Reload Low Byte Registers
The Timer Reload Low Byte registers, detailed in
cant byte (MSB) of the 2-byte timer reload value. In CONTINUOUS mode, the
timer reload value is reloaded into the timer upon end-of-count. When the
RST_EN bit (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.
