AUXM
MODE1
INT1, 0 ... Auxiliary Interrupt from external devices 1, 0
A low level or a negative state transition (programmable in ACFG2.EL1/0) is detected at
pin AUX7 or AUX6, respectively.
4.5.4
Value after reset: FF
For the MASK register following logical states are applied:
0: Interrupt is enabled
1: Interrupt is disabled
Each interrupt source in the AUXI register can selectively be masked/disabled by setting
the corresponding bit in AUXM to ’1’. Masked interrupt status bits are not indicated when
AUXI is read. Instead, they remain internally stored and pending, until the mask bit is
reset to ’0’.
4.5.5
Value after reset: 00
WTC1, 2 ... Watchdog Timer Control 1, 2
After the watchdog timer mode has been selected (RSS = ’11’) the watchdog timer is
started. During every time period of 128 ms the microcontroller has to program the
WTC1 and WTC2 bit in the following sequence
to reset and restart the watchdog timer.
If WTC1/2 is not written fast enough in this way, the timer expires and a WOV-interrupt
(AUXI register) together with a reset pulse is generated.
