UART channel 5 Ring Indicator or general purpose input (active low).
UART channel 6 Transmit Data or infrared transmit data.
UART channel 6 Receive Data or infrared receive data. Normal RXD input
idles at logic 1 condition. The infrared pulses can be inverted internally prior
the decoder by FCTR[4].
UART channel 6 Request to Send or general purpose output (active low).
UART channel 6 Clear to Send or general purpose input (active low).
UART channel 6 Data Terminal Ready or general purpose output (active low).
UART channel 6 Data Set Ready or general purpose input (active low).
UART channel 6 Carrier Detect or general purpose input (active low).
UART channel 6 Ring Indicator or general purpose input (active low).
UART channel 7 Transmit Data or infrared transmit data.
UART channel 7 Receive Data or infrared receive data. Normal RXD input
idles at logic 1 condition. The infrared pulses can be inverted internally prior

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 su-vendor ID during power up or reset. However, it
can be manually clocked thru the Configuration Register REGB.
