17.1.4. 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/tim-
ers 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 sig-
nal as its time base. 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 16 (UART) for information on configur-
ing Timer 1 for baud rate generation.
