Technical Data
NOTE:
These pins provide the reference voltages for the analog-to-digital
converter.
This pin provides two separate functions, depending on the operating
mode. In single chip and bootstrap modes, PG7/R/W acts as
input/output port G bit 7. Refer to
information.
In expanded and test modes, PG7/R/W performs the read/write function.
PG7/R/W signals the direction of transfers on the external data bus. A
high on this pin indicates that a read cycle is in progress.
In the 84-pin PLCC package, 62 pins are arranged into seven 8-bit ports:
A, B, C, E, F, G, and H, and one six-bit port (D). The lines of ports A, B,
C, D, F, G, and H are fully bidirectional; E is input only. Each of the
bidirectional ports serves a purpose other than I/O, depending on the
operating mode or peripheral function selected. Note that ports B, C, F,
and one bit of port G are available for I/O functions only in single chip
and bootstrap modes. Refer to
functions in different operating modes.
When using the information about port functions, do not confuse pin
function with the electrical state of the pin at reset. All general-purpose
I/O pins configured as inputs at reset are in a high-impedance state. Port
data registers reflect the functional state of the port at reset. The pin
function is mode dependent.
