9.3 Timer Interrupt
The TIMER can be programmed to generate an
Interrupt request until the end of the count or when
there is an Timer Stop signal (TSTRT). The Timer
can generate programmable Interrupts into 4 dif-
ferent modes:
Interrupt mode 1: Interrupt on Timer Stop.
Interrupt mode 2: Interrupt on Rising Edge of
TIMEROUT.
Interrupt mode 3: Interrupt on Falling Edge of
TIMEROUT.
Interrupt mode 4: Interrupt on both edges of
TIMEROUT.

The Interrupt mode can be selected by means of
INTSL and INTE bits of the REG_CONF5.
NOTE: the interrupt on TIMEROUT rising edge is
also generated after the Start.
WARNING: If the PWM/Timer is configured with
the Interrupt on Stop and the Start/Stop is
configured as external, a low signal in the STRT
pin determines a PWM/Timer interrupt even if the
peripheral is off. If the interrupt is configured on
falling edge, a reset signal generates an interrupt
request.
