SFR, TCON
Timer 0 and Timer 1 share the SFR, TCON, that
controls these timers and provides information
about them. See
Table 39., page 70
.
Bits IE0 and IE1 are not related to Timer/Counter
functions, but they are set by hardware when a
signal is active on one of the two external interrupt
pins, EXTINT0 and EXTINT1. For system informa-
tion on all of these interrupts, see
Table
16., page 41
, Interrupt Summary.
Bits IT0 and IT1 are not related to Timer/Counter
functions, but they control whether or not the two
external interrupt input pins, EXTINT0 and
EXTINT1 are edge or level triggered.
SFR, TMOD
Timer 0 and Timer 1 have four modes of operation
controlled by the SFR named TMOD (Table
40
).
Timer 0 and Timer 1 Operating Modes
The “Timer” or “Counter” function is selected by
the C/T control bits in TMOD. The four operating
modes are selected by bit-pairs M[1:0] in TMOD.
Modes 0, 1, and 2 are the same for both Timer/
Counters. Mode 3 is different.
Mode 0.
Putting either Timer/Counter into Mode 0
makes it an 8-bit Counter with a divide-by-32 pre-
scaler. Figure
22
shows Mode 0 operation as it ap-
plies to Timer 1 (same applies to Timer 0).
In this mode, the Timer Register is configured as a
13-bit register. As the count rolls over from all '1s'
to all '0s,' it sets the Timer Interrupt flag TF1. The
counted input is enabled to the Timer when
TR1 = 1 and either GATE = 0 or EXTINT1 = 1.
(Setting GATE = 1 allows the Timer to be con-
trolled by external input pin, EXTINT1, to facilitate
pulse width measurements). TR1 is a control bit in
the SFR, TCON. GATE is a bit in the SFR, TMOD.
The 13-bit register consists 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.
Mode 0 operation is the same for the Timer 0 as
for Timer 1. Substitute TR0, TF0, C0, TL0, TH0,
and EXTINT0 for the corresponding Timer 1 sig-
nals in Figure
22
. There are two different GATE
Bits, one for Timer 1 and one for Timer 0.
Mode 1.
Mode 1 is the same as Mode 0, except
that the Timer Register is being run with all 16 bits.
Mode 2.
Mode 2 configures the Timer Register as
an 8-bit Counter (TL1) with automatic reload, as
shown in
Figure 23., page 73
. Overflow from TL1
not only sets TF1, but also reloads TL1 with the
contents of TH1, which is preset with firmware.
The reload leaves TH1 unchanged. Mode 2 oper-
ation 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 24., page 73
. TL0 uses the
Timer 0 control Bits: C/T, GATE, TR0, and TF0, as
well as the pin EXTINT0. TH0 is locked into a timer
function (counting at a rate of 1/12 f
OSC
) and takes
over the use of TR1 and TF1 from Timer 1. Thus,
TH0 now controls the “Timer 1“ interrupt flag.
Mode 3 is provided for applications requiring an
extra 8-bit timer on the counter (see
Figure
24., page 73
). With Timer 0 in Mode 3, a
uPSD33xx device can look like it has three Timer/
Counters (not including the PCA). 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, or can
still be used by the serial port as a baud rate gen-
erator, or in fact, in any application not requiring an
interrupt.
