TH and TL—Timer High and Low Bytes
These 2 bytes, {TMRH[7:0], TMRL[7:0]}, contain the current 16-bit timer count value.
The Timer 0-3 Reload High and Low Byte (TxRH and TxRL) registers (see
Table 42
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.
