ST92141 - GENERAL DESCRIPTION
Table 4. ST92141 Alternate functions
How to configure the I/O ports
To configure the I/O ports, use the information in
Table 3
Table in the I/O Ports Chapter on
I/O note = The hardware characteristics fixed for
each port line in
All I/O inputs have Schmitt trigger fixed by hard-
ware so selecting CMOS or TTL input by software

has no effect, the input will always be Schmitt Trig-
ger. In particular, the Schmitt Triggers present on
the P5[7:2] pins have a standard hysteresis
whereas the remaining pins have Schmitt Triggers
with High Hysteresis (refer to Electrical Specifica-
tions).
