UART channel 7 Receive Data or infrared receive data. Normal RXD input
idles at HIGH condition. The infrared pulses can be inverted prior to decoding
by setting FCTR bit [4].
UART channel 7 Request to Send or general purpose output (active LOW).
UART channel 7 Clear to Send or general purpose input (active LOW).
UART channel 7 Data Terminal Ready or general purpose output (active
LOW).
UART channel 7 Data Set Ready or general purpose input (active LOW).
UART channel 7 Carrier Detect or general purpose input (active LOW).
UART channel 7 Ring Indicator or general purpose input (active LOW).
Multi-purpose input/output 0. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT
Multi-purpose input/output 1. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
Multi-purpose input/output 2. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
Multi-purpose input/output 3. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
Multi-purpose input/output 4. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
Multi-purpose input/output 5. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
Multi-purpose input/output 6. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
Multi-purpose input/output 7. The function of this pin is defined thru the Con-
figuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and MPIOINT.
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.
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.
Write data to EEPROM device. It is manually accessible thru the Configura-
tion Register REGB.
Read data from EEPROM device. It is manually accessible thru the Configu-
ration Register REGB.
Crystal or external clock input.
Crystal or buffered clock output.
