UART channel 2 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 2 Request to Send or general purpose output (active LOW).
UART channel 2 Clear to Send or general purpose input (active LOW).
UART channel 2 Data Terminal Ready or general purpose output (active
LOW).
UART channel 2 Data Set Ready or general purpose input (active LOW).
UART channel 2 Carrier Detect or general purpose input (active LOW).
UART channel 2 Ring Indicator or general purpose input (active LOW).
UART channel 3 Transmit Data or infrared transmit data.
UART channel 3 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 3 Request to Send or general purpose output (active LOW).
UART channel 3 Clear to Send or general purpose input (active LOW).
UART channel 3 Data Terminal Ready or general purpose output (active
LOW).
UART channel 3 Data Set Ready or general purpose input (active LOW).
UART channel 3 Carrier Detect or general purpose input (active LOW).
UART channel 3 Ring Indicator or general purpose input (active LOW).
Expansion Interface Mode Select. Connect this pin to VCC to enable master
mode or when there is no slave device. Connect this pin to GND when the
device is in slave mode.
Expansion Interface Clock. In master mode, this pin is the clock output to the
slave device. In slave mode, this pin is the clock input from the master
device. The expansion interface clock is 62.5MHz. The UARTs on the slave
device will need to use different baud rate generator divisors than the master
device. The trace capacitance between the master and slave device must be
less than 25pF.
Expansion Interface Data 7 (MSB). The trace capacitance between the mas-
ter and slave device must be less than 25pF.
Expansion Interface Data 6. The trace capacitance between the master and
slave device must be less than 25pF.
Expansion Interface Data 5. The trace capacitance between the master and
slave device must be less than 25pF.
Expansion Interface Data 4. The trace capacitance between the master and
slave device must be less than 25pF.
