6.5.4 Mode 3
When timer 1 is in Mode 3 it is stopped (holds its count). 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 and Timer 0 is shown in Figure 17. TL0 uses the Timer 0 control bits: T0C/T,
T0GATE, TR0, INT0, and TF0. 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, the P89V660/662/664 can look like it has an additional Timer.
Note: 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.
6.6 Timer 2
Timer 2 is a 16-bit Timer/Counter which can operate as either an event timer or an event
counter, as selected by C/T2 in the special function register T2CON. Timer 2 has four
operating modes: Capture, Auto-reload (up or down counting), Clock-out, and Baud Rate
Generator which are selected according to Table 31 using T2CON (Table 32 and
