6.4
For the P8xCL883/P8xCL884, MIN is no longer the
alternative function of P4.0, but MIN is a separate pin.
The polarity of MIN can however still be programmed with
the P4.0 bit. P4.0 is a data SFR but no port logic is
connected.
Only the most significant bits of MOUT, i.e. MOUT2 and
MOUT1 are directly available as separate pins. In order to
be able to further increase the signal quality, the MOUT0
signal is available as an alternative port function of P3.1.

Register (ALTP); see Section 6.2.3.

The Watchdog Timer differs from the description in the
“TELX family” data sheet in that the external EW pin does
not exist on the P8xCL883/P8xCL884.
