ST92195B - GENERAL DESCRIPTION

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 ST92195B may as-

sume software programmable Alternate Functions

(see Table 1).
