19.1.4. Mode 3: Two 8-bit Counter/Timers (Timer 0 Only)
Timer 0 and Timer 1 behave differently in Mode 3. Timer 0 is configured as two separate 8-bit counter/timers held
in TL0 and TH0. The counter/timer in TL0 is controlled using the Timer 0 control/status bits in TCON and TMOD:
TR0, C/T0, GATE0 and TF0. It can use either the system clock or an external input signal as its timebase. The
TH0 register is restricted to a timer function sourced by the system clock. TH0 is enabled using the Timer 1 run
control bit TR1. TH0 sets the Timer 1 overflow flag TF1 on overflow and thus controls the Timer 1 interrupt.
Timer 1 is inactive in Mode 3, so with Timer 0 in Mode 3, Timer 1 can be turned off and on by switching it into and
out of its Mode 3. When Timer 0 is in Mode 3, Timer 1 can be operated in Modes 0, 1 or 2, but cannot be clocked
by external signals nor set the TF1 flag and generate an interrupt. However, the Timer 1 overflow can be used for
baud rate generation. Refer to Section 18 (UART) for information on configuring Timer 1 for baud rate generation.
