Mode 1:
Mode 1 is the same as Mode 0, except that the Timer
register is run with all 16 bits. The clock is applied to the
combined high and low timer registers (TL1/TH1). As
clock pulses are received, the timer counts up: 0000H,
0001H, 0002H, etc. An overflow occurs on the FFFFH-to-
0000H overflow flag. The timer continues to count. The
overflow flag is the TF1 bit in TCON that is read or written
by software (see Figure 9).
Mode 2:
Mode 2 configures the Timer register as an 8-bit Counter
(TL1) with automatic reload, as shown in Figure 10.
Overflow from TL1 not only sets TF1, but also reloads TL1
with the contents of TH1, which is preset by software. The
reload leaves the TH1 unchanged. Mode 2 operation is
the same for Timer/Counter 0.
Mode 3:
Timer 1 in Mode 3 simply holds its count. The effect is the
same as setting TR1 = 0. Timer 0 in Mode 3 establishes
TL0 and TH0 as two separate counters. The logic for
Mode 3 on Timer 0 is shown in Figure 10. TL0 uses the
Timer 0 control bits: C/T, GATE, TR0, INT0, and TF0. TH0
is locked into a timer function (counting machine cycles)
and over the use of TR1 and TF1 from Timer 1. Thus, TH0
now controls the Timer 1 interrupt.
Mode 3 is for applications requiring an extra 8-bit timer or
counter. With Timer 0 in Mode 3, the IS80LV51/31 can
appear to have three Timer/Counters, and an IS80LV52/
32 can appear to have four. When Timer 0 is in Mode 3,
Timer 1 can be turned on and off by switching it out of and
into its own Mode 3. In this case, Timer 1 can still be used
by the serial port as a baud rate generator or in any
application not requiring an interrupt.
