Figure 11. Timer/Counter Mode 0 & Mode 1

Mode 1

Mode 1 is similar to Mode 0 except that the counting register forms a 16 bit counter, rather than a 13

bit counter. This means that all the bits of THx and TLx are used. Roll-over occurs when the timer

moves from a count of FFFFh to 0000h. The timer overflow flag TFx of the relevant timer is set and if

enabled an interrupt will occur. The selection of the time-base in the timer mode is similar to that in

Mode 0. The gate function operates similarly to that in Mode 0.

Mode 2

In Mode 2, the timer/counter is in the Auto Reload Mode. In this mode, TLx acts as a 8 bit count

bit in TCON is set and TLx is reloaded with the contents of THx, and the counting process continues

from here. The reload operation leaves the contents of the THx register unchanged. Counting is

enabled by the TRx bit and proper setting of GATE and

INTx

pins. As in the other two modes 0 and 1

mode 2 allows counting of either clock cycles (clock/12 or clock/4) or pulses on pin Tn.
