Signal Summary
TXD2 / QGPO2 / C_CNTX06
1
O
QGPO2
Transmit Data 2. This is the serial data output from the SCI2
O
Port QGPO 2. When this signal is not needed for SCI
applications it can be configured as general-purpose output.
When the transmit enable bit in the SCI control register is set
to a logic 1, this signal cannot function as a general-purpose
output.
O
TouCAN Transmit Data. This signal is the serial data output
for the TouCAN_C module.
RXD1 / QGPI1
1
I
QGPI1
Receive Data 1. This input signal is the serial data input to
the SCI.
I
Port QGPI 1. When this signal is not needed for SCI
applications, it can be configured as a general-purpose
input. When the receive enable bit in the SCI control register
is set to a logic 1, this signal cannot function as a
general-purpose input.
RXD2 / QGPI2 / C_CNRX06
1
I
QGPI2
Receive Data 2. This input signal provides serial data input
to the SCI2.
I
Port QGPI 2. When this signal is not needed for SCI
applications it can be configured as a general-purpose input.
When the receive enable bit in the SCI control register is set
to a logic 1, this signal cannot function as a general-purpose
input.
I
TouCAN Receive Data. This is the serial data input signal for
the TouCAN_C module.
MIOS14
MDA[11:15, 27:31]
10
I/O
MDA[11:15,
27:31]
Double Action. These 10 signals provide paths for two 16-bit
input captures and two 16-bit output compares.
Clock and Load inputs:
MDA11 can provide clock inputs to the modulus counter
submodule, MMCSM6
MDA12 can provide load inputs to the modulus counter
submodule, MMCSM6
MDA13 can provide clock inputs to MMCSM22
MDA14 can provide load inputs to MMCSM22
MDA27 can provide clock inputs to MMCSM23
MDA28 can provide load inputs to MMCSM23
MDA30 can provide clock inputs to MMCSM7
MDA31 can provide load inputs to MMCSM7
MPWM0 / MDI1
1
I/O
MPWM0 unless
the Nexus
(READI) port is
enabled, then
MDI1.
Pulse Width Modulation 0. This signal provides variable
pulse width outputs at a wide range of frequencies.
I
Message Data In. MDI1 is a Nexus input signal used for
downloading configuration information, writes to user
resources, etc. Internal latching of MDI will occur on rising
edge of MCKI.
