Timer 0 Reload High and Low Byte Registers
The Timer 0 Reload High and Low Byte (T0RH and T0RL) registers, shown in Tables 60
and 61, store a 16-bit reload value, {TRH[7:0], TRL[7:0]}. Values written to the Timer
Reload High Byte Register are stored in a temporary holding register. When a Write to the
Timer Reload Low Byte Register occurs, the temporary holding register value is written to
the Timer High Byte Register. This operation allows simultaneous updates of the 16-bit
timer reload value.
