48-96 Kbyte ROM HCMOS MCU WITH ON-SCREEN DISPLAY AND TELETEXT DATA SLICER

STMicroelectronics 

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).

ST92195C/D - GENERAL DESCRIPTION

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 ST92195C/D may

assume software programmable Alternate Func-

tions (see Table 1).
