as the NMSI1 pins (see the previous description). The input buffers have Schmitt triggers.
TCLK3 acts as the SCC3 baud rate generator output if SCC3 is in one of the multiplexed
modes.

5.16 IDMA OR PORT A PINS
The IDMA or port A pins are shown in Figure 5-13.
Each of these three pins can be used either as dedicated pins for the IDMA signals or as
general-purpose parallel I/O port A pins. Note that even if one or more of the IDMA pins are
used as general-purpose I/O pins, the IDMA can still be used. For example, if DONE is not
needed by the IDMA, it can be configured as a general-purpose I/O pin. If the IDMA is used
for memory-to-memory transfers only, then all three pins can be used as general-purpose
I/O pins. The input buffer of DACK has a Schmitt trigger.

• RXD3/PA8
• TXD3/PA9
• RCLK3/PA10
• TCLK3/PA11
This signal functions as the SCP receive data input or may be used as the NMSI3 CTS
input pin.
This output is the SCP transmit data output or may be used as the NMSI3 RTS pin.
This bidirectional signal is used as the SCP clock output or the NMSI3 CD3 input pin.
This pin functions as bit 12 of port A or may be used as the SCC3 baud rate generator
output clock when SCC3 is operating in NMSI mode.
