25.1. Timer 0 and Timer 1
Timer 0 and Timer 1 are each implemented as a16-bit register accessed as two separate bytes: a low byte
(TL0 or TL1) and a high byte (TH0 or TH1). The Counter/Timer Control register (TCON) is used to enable
Timer 0 and Timer 1 as well as indicate status. Timer 0 interrupts can be enabled by setting the ET0 bit in
the IE register. Timer 1 interrupts can be enabled by setting the ET1 bit in the IE register. Both counter/
timers operate in one of four primary modes selected by setting the Mode Select bits T1M1–T0M0 in the
Counter/Timer Mode register (TMOD). Each timer can be configured independently for the operating
modes described below.
