Figure 22. Timer/Counter Mode 2: 8-bit Auto-reload
Figure 23. Timer/Counter Mode 3: Two 8-bit Counters
Mode 2.
Mode 2 configures the Timer register as
an 8-bit Counter (TL1) with automatic reload, as
shown in Figure 22. Overflow from TL1 not only
sets TF1,but also reloads TL1 with the contents of
TH1, which is preset by software. The reload
leaves TH1 unchanged. Mode 2 operation is the
same for Timer/Counter 0.
Mode 3.
Timer 1in Mode3 simply holds its count.
The effect is the same as setting TR1 = 0.
Timer 0 inMode 3 establishes TL0 and TH0as two
separate counters. The logic for Mode 3 on Timer
0 is shown in Figure 23.TL0 uses the Timer 0 con-
trol bits: C/T, GATE, TR0, INT0, and TF0. TH0 is
locked into a timer function (counting machine cy-
cles) and takes over the use of TR1 and TF1 from
Timer 1. Thus, TH0 now controls the “Timer 1“ in-
terrupt.
Mode 3 is provided for applications requiring an
extra 8-bit timer on the counter. With Timer 0 in
Mode 3, an
μ
PSD3200 Family can look like it has
three Timer/Counters. When Timer 0 is in Mode 3,
Timer 1 can be turnedon and offby switching itout
of and into its own Mode 3, or can still be used by
