ST7 MDT20 EVAL BOARD DESCRIPTION
1.8 SCI DEVICE COMMUNICATION
The DB9 connector can be used to link the ST7 MDT20 Eval Board to a PC, for example. A
“MAX232” component is used to fit the ST7 TTL output to the line level of a PC serial con-
nector.
1.9 I/O PORT FUNCTIONS
All I/O port pins are accessible through external connectors (connector JP3 for port A, JP4 for
port B, JP5 for port C, JP6 for port D, JP2 for port E, JP7 for port F).
1.9.1 Port A
The PA0 pin can be used to generate an external interrupt (EI0). It is connected to the ground
through push-button switch SW1.
Pins PA2 and PA3 are used to validate the 7-segment LED displays (useful for multiplexing).
1.9.2 Port B
Pins PB5, PB6, PB7 are connected to 3 LEDs.
Pins PB0 and PB4 can be used to generate an external interrupt (EI2 and EI3). These pins are
connected to the ground through push-button switches SW3 and SW4.

1.9.3 Port C
Table 2. Port C Alternate Functions
1.9.4 Port D
This port is connected to the 7-segment LED which is validated with a ‘1’ logical value on pins
PA2 and PA3.
