Counter Operation
Reload mode
When the 16-bit down counter underflows (“0000
H
” to “FFFF
H
”) , the value of the 16-bit reload register (TMRLR)
is loaded into the 16-bit down counter, and count operation is conducted. In addition, when an underflow occurs
an interrupt request is output, so this can also be used as an interval timer. It is possible to output the inverted
toggle waveform from the TO pin with each underflow.

Values in parentheses ( ) are when machine clock frequency is 16 MHz.
One-shot mode
When the 16-bit down counter underflows (“0000
H
” to “FFFF
H
”) , count operation is halted.
Reference :
16-bit reload timer 0 can be used to create the UART baud rate.
16-bit reload timer 1 can be used as the start trigger for the A/D converter.
