ST92195B - GENERAL INFORMATION
PIN DESCRIPTION (Cont’d)
P0[7:0], P2[5:0], P3[7:4], P4[7:0], P5[1:0]
I/O Port Lines
(Input/Output, TTL or CMOS com-
patible).
28 lines grouped into I/O ports, bit programmable
as general purpose I/O or as Alternate functions
(see I/O section).
Important
: Note that open-drain outputs are for
logic levels only and are not true open drain.
1.2.1 I/O Port Alternate Functions.
Each pin of the I/O ports of the ST92195 may as-
sume software programmable Alternate Functions
(see Table 1).
