Timer Reload High and Low Byte Registers
Description
Timer Reload Register High and Low
These two bytes form the 16-bit reload value, {TRH[7:0], TRL[7:0]}. This value sets the max-
imum count value, which initiates a timer reload to 0001H. In COMPARE Mode, these two
bytes form the 16-bit compare value.

The Timer 0–1 Reload High and Low Byte (TxRH and TxRL) registers, shown in
Tables 52 and 53, 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. In COMPARE Mode, the Timer Reload High and Low Byte
registers store the 16-bit compare value.
