18.8.1.3 Mode 2
Mode 2 operation is the same for Timer 0 and Timer 1. In mode 2, the timer is
configured as an 8-bit counter, with automatic reload of the start value. The LSB register
(TL0 or TL1) is the counter, and the MSB register (TH0 or TH1) stores the reload value.
As illustrated in Figure 19 Timer 0/1 – Mode 2, mode 2 counter control is the same as
for mode 0 and mode 1. However, in mode 2, when TLn increments from 0xFF, the
value stored in THn is reloaded into TLn.
