8-BIT TIMER (Cont’d)
8.2.4.2 Event Counter Mode
(TOUT = “0”, DOUT = “0”)
In this mode, the TIMER pin is the input clock of
the Timer prescaler which is decremented on eve-
ry rising edge of the input clock (allowing event
count). See
Figure 30
and
Figure
This mode is selected by clearing the TOUT bit in
the TSCR register (i.e. as input) and clearing the
DOUT bit.
Note: In this mode, if the TIMER pin is multi-
plexed, the corresponding port control bits have to
be set in input with pull-up configuration.

8.2.4.3 Output Mode
(TOUT = “1”, DOUT = “data out”)
In Output mode, the TIMER pin is connected to the
DOUT latch, hence the Timer prescaler is clocked

INT
The user can select the prescaler division ratio us-
ing the PS[2:0] bits in the TSCR register. When TCR
decrements to zero, 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 and
has to be cleared by the user. The low-to-high TMZ
ST6208C/ST6209C/ST6210C/ST6220C
bit transition is used to latch the DOUT bit in the
TSCR and, if the TOUT bit is set, DOUT is trans-
ferred to the TIMER pin. This operating mode allows
external signal generation on the TIMER pin. See

the TSCR register (i.e. as output) and setting the
DOUT bit to output a high level or clearing the
DOUT bit to output a low level.
Note: As soon as the TOUT bit is set, The timer
pin is configured as output push-pull regardless of
the corresponding I/O port control registers setting
(if the TIMER pin is multiplexed).
