programmable. All port D lines are configured as input during power
on or external reset.
When the SPE bit of the SPI Control register (bit 6 of address $10) is
set, PD5, PD6, & PD7 are used for SDI, SDO, & SCK respectively, for
the Serial Peripheral Interface. PD5 to PD7 are not bonded out on the
56-pin package. Hence, the 56-pin package does not have SPI
features.
PE0-PE7
30-23
26-19
These eight I/O lines comprise port E.The state of any pin is software
programmable. All port E lines are configured as input during power
on or external reset.
PF0-PF7
42-35
38-31
These eight I/O lines comprise port F. The state of any pin is software
programmable. All port F lines are configured as input during power
on or external reset.

64, 63
These two I/O lines comprise port G. The state of any pin is software
programmable. All port G lines are configured as input during power
on or external reset. PG1 is not bonded out on the 56-pin package.
ENCOOUT
