ANCILLARY SIGNALS
MPIO0
108
I/O
Multi-purpose input/output 0. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT
MPIO1
107
I/O
Multi-purpose input/output 1. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
MPIO2
74
I/O
Multi-purpose input/output 2. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
MPIO3
73
I/O
Multi-purpose input/output 3. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
MPIO4
68
I/O
Multi-purpose input/output 4. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
MPIO5

figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
EECK
116
O
Serial clock to EEPROM. An internal clock of CLK divide by 256 is used for
reading the vendor and sub-vendor ID during power up or reset. However, it
can be manually clocked thru the Configuration Register REGB.
EECS
115
O
Chip select to a EEPROM device like 93C46. It is manually selectable thru
the Configuration Register REGB. Requires a pull-up 4.7K ohm resistor for
external sensing of EEPROM during power up. See DAN112 for further
details.
EEDI
114
O
Write data to EEPROM device. It is manually accessible thru the Configura-
tion Register REGB.
EEDO
113
I
Read data from EEPROM device. It is manually accessible thru the Configu-
ration Register REGB.
XTAL1
110
I
Crystal or external clock input.
XTAL2
109
O
Crystal or buffered clock output.
