a control bit in the Special Function Register TCON. GATE is in TMOD. The 13-bit register con-
sists of all 8 bits of TH1 and the lower 5 bits of TL1. The upper 3 bits of TL1 are indeterminate
and should be ignored. Setting the run flag (TR1) does not clear the registers. See Figure 16-1.
Figure 16-1. Timer/Counter 1 Mode 0: Variable Width Counter
Mode 0 operation is the same for Timer 0 as for Timer 1, except that TR0, TF0 and INT0 replace
the corresponding Timer 1 signals in Figure 16-1. There are two different GATE bits, one for
Timer 1 (TMOD.7) and one for Timer 0 (TMOD.3).
16.2
Mode 1
In Mode 1 the Timers are configured for 16-bit auto-reload. The Timer register is run with all 16
bits. The 16-bit reload value is stored in the high and low reload registers (RH1/RL1). The clock
is applied to the combined high and low timer registers (TH1/TL1). As clock pulses are received,
the timer counts up: 0000H, 0001H, 0002H, etc. An overflow occurs on the FFFFH-to-0000H
transition, upon which the timer register is reloaded with the value from RH1/RL1 and the over-
flow flag bit in TCON is set. See Figure 16-2. The reload registers default to 0000H, which gives
the full 16-bit timer period compatible with the standard 8051. Mode 1 operation is the same for
Timer/Counter 0.
