Mode 1
Mode 1 is the same as Mode 0, except that all 16 bits of the timer
register (THn and TLn) are used. (See Figures 26 and 27)
Mode 2
Mode 2 configures the Timer register as an 8-bit Counter (TLn) with
automatic reload, as shown in Figures 28 and 29. Overflow from TLn
not only sets TFn, but also reloads TLn with the contents of THn,
which must be preset by software. The reload leaves THn
unchanged. Mode 2 operation is slightly different for Timer 0 and
Timer 1 (see Figures 28 and 29).
Mode 3
When Timer 1 is in Mode 3 it is stopped. The effect is the same as
setting TR1 = 0.
Timer 0 in Mode 3 establishes TL0 and TH0 as two separate 8-bit
counters. The logic for Mode 3 on Timer 0 is shown in Figure 30.
TL0 uses the Timer 0 control bits: C/T, GATE, TR0, and TF0 as well
as the INT0 pin. TH0 is locked into a timer function (counting
machine cycles) and takes over the use of TR1 and TF1 from Timer
1. Thus, TH0 now controls the “Timer 1” interrupt.
Mode 3 is provided for applications that require an extra 8-bit timer.
With Timer 0 in Mode 3, an P87LPC761 can look like it has three
Timer/Counters. When Timer 0 is in Mode 3, Timer 1 can be turned
on and off by switching it into and out of its own Mode 3. It can still
be used by the serial port as a baud rate generator, or in any
application not requiring an interrupt.
