USER’S MANUAL
Pin Name: mosi_qgpio5
Master-Out Slave-In (MOSI) – This bi-directional signal furnishes serial data output
from the QSPI in master mode and serial data input to the QSPI in slave mode.
QGPIO[5] – When this pin is not needed for a QSPI application it can be configured
as a general purpose input/output.
Pin Name: sck_qgpio6
SCK – This bi-directional signal furnishes the clock from the QSPI in master mode or
furnishes the clock to the QSPI in slave mode.
QGPIO[6] – When this pin 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 pin can not function as a GPIO.
Pin Name: txd1_qgpo1 - txd2_qgpo2 (2 pins)
Transmit Data – These output signals are the serial data outputs from the SCI1 and
SCI2.
QSCI GPO[1:2] – When these pins are not needed for a 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 pins can not function as general purpose outputs
Pin Name: rxd1_qgpi1 - rxd2_qgpi2 (2 pins)
Receive Data – These input signals furnish serial data inputs to the SCI1 and SCI2.
QSCI GPI[1:2] – When these pins are not needed for SCI applications they can be
configured as general purpose inputs. When the receive enable bit in the SCI control
register is set to a logic 1, these pins can not function as general purpose inputs.
Pin Name: eck
External Baud Clock – This signal provides an external baud clock used by SCI1 and
SCI2.
