Signal Summary
VSSA
1
I
VSSA
VSSA. Ground level for analog subsystems of the
QADC64E_A and QADC64E_B modules.
QSMCM
PCS0 / SS / QGPIO0
1
I/O
QGPIO0
PCS0. This signal provides QSPI peripheral chip select 0 for
the QSMCM module.
I/O
SS. Assertion of this bidirectional signal places the QSPI in
slave mode.
I/O
Port QGPIO0. When this signal is not needed for a QSPI
application it can be configured as a general-purpose
input/output.
PCS[1:3] / QGPIO[1:3]
3
I/O
QGPIO[1:3]
PCS[1:3]. These signals provide QSPI peripheral chip
selects for the QSMCM module.
I/O
Port QGPIO[1:3]. When these signals are not needed for
QSPI applications they can be configured as
general-purpose input/outputs.
MISO / QGPIO4
1
I/O
QGPIO4
Master-In Slave-Out (MISO). This bidirectional signal is the
serial data input to the QSPI in master mode, and serial data
output from the QSPI in slave mode.
I/O
Port QGPIO4. When this signal is not needed for a QSPI
application it can be configured as a general-purpose
input/output.
MOSI / QGPIO5
1
I/O
QGPIO5
Master-Out Slave-In (MOSI). This bidirectional signal is the
serial data output from the QSPI in master mode and serial
data input to the QSPI in slave mode.
I/O
Port QGPIO5. When this signal is not needed for a QSPI
application it can be configured as a general-purpose
input/output.
SCK / QGPIO6
1
I/O
QGPIO6
SCK. This bidirectional signal is the clock from the QSPI in
master mode or is the clock to the QSPI in slave mode.
I/O
Port QGPIO6 for the QSMCM module. When this signal is
not needed for a QSPI application it can be configured as a
general-purpose input/output. When the QSPI is enabled for
serial transmitting, the signal cannot function as a GPIO.
TXD1 / QGPO1
1
O
QGPO1
Transmit Data 1. This is the serial data output from the SCI1.
O
Port QGPO 1. When these signals are not needed for SCI
applications, they can be configured as general-purpose
outputs. When the transmit enable bit in the SCI control
register is set to a logic 1, these signals cannot function as
general-purpose outputs.
