DX1 / AXR0[5]:
This pin has a dual function:
• If configured for McBSP usage, this pin is the data transmit output of McBSP1. All outgoing
data to devices, connected to the McBSP1 is communicated via this output pin. If the
transmitter port function is not needed, DX1 can also be used as general purpose output.
• If configured for McASP usage, this pin is a bi-directional data line of McASP0.
DX1 has a 22R series resistor. How to use this pin is described in [4], [6] and [7].
CLKR1 / AXR0[6]:
This pin has a dual function:
• If configured for McBSP usage, this pin is the receiver clock output or input of McBSP1.
The receiver clock signal can be either supplied by an external clock or can be provided
internally and then supplied to the pin. If the receiver port function is not needed, CLKR1
can also be used as general purpose I/O pin.
• If configured for McASP usage, this pin is a bi-directional data line of McASP0.
CLKR1 has a 22R series resistor. How to use this pin is described in [4] and [6] and [7].
CLKX1 / AMUTE0:
This pin has a dual function:
• If configured for McBSP usage, this pin is the transmitter clock output or input of McBSP1.
This transmitter clock can either be supplied by an external clock or can be provided
internally and then supplied to the pin. If the transmitter port function is not needed, CLKX1
can also be used as general purpose I/O pin.
• If configured for McASP usage, this pin is the mute output of McASP0.
CLKX1 has a 22R series resistor. How to use this pin is described in [4] and [6] and [7].
FSR1 / AXR0[7]:
This pin has a dual function:
• If configured for McBSP usage, this pin is the receiver frame sync input or output of
McBSP1. If frame synchronization is provided by an external device, FSR1 is an input. If
the frame synchronization signals are generated internally by processor's sample rate
generator, FSR1 is an output. If the receiver port function is not needed, FSR1 can also be
used as general purpose I/O pin.
• If configured for McASP usage, this pin is a bi-directional data line of McASP0.
FSR1 has a 22R series resistor. How to use this pin is described in [4], [6] and [7].
FSX1:
This pins is the transmitter frame sync output or input of McBSP1. If frame synchronization is
provided by an external device, FSX1 is an input. If the frame synchronization signals are
generated internally by the processor's sample rate generator, FSX1 is an output. If the transmitter
port function is not needed, FSX1 can also be used as general purpose I/O pin.
FSX1 has a 22R series resistor. How to use this pin is described in [4] and [6].
