4.2.1 Timer Operating Modes
There are three operating modes, which are se-
lected by the TOUT and DOUT bits (see TSCR
register). These three modes correspond to the
two clocks which can be connected to the 7-bit
prescaler (f
÷ 12 or TIMER pin signal), and to
INT
the output mode.
Gated Mode
(TOUT = “0”, DOUT = “1”)
In this mode the prescaler is decremented by the
Timer clock input (f
÷ 12), but ONLY when the
INT
signal on the TIMER pin is held high (allowing
pulse width measurement). This mode is selected
by clearing the TOUT bit in the TSCR register to
“0” (i.e. as input) and setting the DOUT bit to “1”.
PC1 must be configured in input mode
Event Counter Mode
(TOUT = “0”, DOUT = “0”)
In this mode, the TIMER pin is the input clock of
the prescaler which is decremented on the rising
edge.
Output Mode
(TOUT = “1”, DOUT = data out)

The TIMER pin is connected to the DOUT latch,
hence the Timer prescaler is clocked by the pres-
caler clock input (f
The user can select the desired prescaler division
ratio through the PS2, PS1, PS0 bits. When the
TCR count reaches 0, it sets the TMZ bit in the
TSCR. The TMZ bit can be tested under program
control to perform a timer function whenever it
goes high. The low-to-high TMZ bit transition is
used to latch the DOUT bit of the TSCR and trans-
fer it to the TIMER pin. This operating mode allows
external signal generation on the TIMER pin.

4.2.2 Timer Interrupt
When the counter register decrements to zero with
the ETI (Enable Timer Interrupt) bit set to one, an
interrupt request is generated as described in the
Interrupt Chapter. When the counter decrements
to zero, the TMZ bit in the TSCR register is set to
one.
