Table 12–2. Timer Control Register Field Descriptions
Bitfield Description
FUNC Function of TOUT pin
FUNC = 0: TOUT is a general-purpose output pin.
FUNC = 1: TOUT is a timer output pin.
DATOUT Data output
When FUNC = 0: The DATOUT is driven on TOUT.
When FUNC = 1: The TSTAT is driven on TOUT after inversion by INVOUT.
DATIN Data in: Value on TINP pin
GO GO bit. Resets and starts the timer counter.
GO = 0: No effect on the timers.
GO = 1: If HLD = 1, the counter register is zeroed and begins counting on the next clock.
12-4
Table 12–1 describes the three registers that configure timer operation.
Name Description
Timer Control Determines the operating mode of the timer, monitors
the timer status, and controls the function of the TOUT
pin.
Timer Period Contains the number of timer input clock cycles to count.
This number controls the TSTAT signal frequency.
Timer Counter Current value of the incrementing counter
Figure 12–2 shows the timer control register. Table 12–2 describes the fields
in this register.
