After the watchdog timer mode has been selected (STCR:TSF = CIX0:RSS = 1) the
watchdog timer is started.
During every time period of 128 ms the processor has to program the WTC1- and
WTC2 bit in the following sequence:
to reset and restart the watchdog timer.
If not, the timer expires and a WOV interrupt (EXIR) together with a reset pulse is
generated.
Test Mode
In test mode (TEM = 1, PFS = 0) all layer-1 functions are disabled and the
ISAC-S TE behaves like an ICC (PEB 2070) device.
Prefilter Select
These bits together determine the pre-filter delay compensation and the test mode
(layer 1 disabled) of the ISAC-S TE, as follows:
IOM OFF. Used in terminal mode (SPCR:SPM = 0).
0: IOM interface is operational
1: IOM interface is switched off (DCL, FSC1, IDP0/1, BCL high impedance).
IOF should be set to "1" if external devices connected to the IOM interface should be
"disconnected" e.g. for power saving purposes or for not disturbing the internal IOM
connection between layer 2 and layer 1. However, the internal operation is
independent of the IOF bit.
