Timers and Counters
The 80515 has two 16-bit timer/counter registers: Timer 0 and Timer 1. These registers can be
configured for counter or timer operations.
In timer mode, the register is incremented every machine cycle, meaning that it counts up after every 12
periods of the MPU clock signal.
In counter mode, the register is incremented when the falling edge is observed at the corresponding input
signal T0 or T1 (T0 and T1 are the timer gating inputs derived from USR[0:7] pins, see the User (USR)
Ports section). Since it takes 2 machine cycles to recognize a 1-to-0 event, the maximum input count
rate is 1/2 of the oscillator frequency. There are no restrictions on the duty cycle, however to ensure
proper recognition of 0 or 1 state, an input should be stable for at least 1 machine cycle.
Four operating modes can be selected for Timer 0 and Timer 1. Two Special Function Registers (TMOD
and TCON) are used to select the appropriate mode.
The Timer 0 load registers are designated as TL0 and TH0 and the Timer 1 load registers are designated
as TL1 and TH1.

Gate
If set, enables external gate control (USR pin(s) connected to T0 or T1 for
Counter 0 or 1, respectively). When T0 or T1 is high, and TRx bit is set (see
the TCON register), a counter is incremented every falling edge on T0 or T1
input pin. If not set, the TRx bit controls the corresponding timer.
TMOD.6
TMOD.2
C/T
Selects Timer or Counter operation. When set to 1, the counter operation is
performed based on the falling edge of T0 or T1. When cleared to 0, the
corresponding register will function as a timer.
TMOD.5
TMOD.1
M1
Selects the mode for Timer/Counter 0 or Timer/Counter 1, as shown in the
TMOD description.
TMOD.4
TMOD.0
M0
Selects the mode for Timer/Counter 0 or Timer/Counter 1, as shown in the
TMOD description.

If Timer 1 M1 and M0 bits are set to '1', Timer 1 stops. If Timer 0 M1
and M0 bits are set to '1', Timer 0 acts as two independent 8-bit
Timer/Counters.
