ESAI_1 DATA AND CONTROL PINS
The ESAI_1 has 6 dedicated pins and shares 4 pins with the ESAI. The pins are described in
the following sections.
11.2.1
SERIAL TRANSMIT 0 DATA PIN (SDO0_1)
SDO0_1 transmits data from the TX0_1 serial transmit shift register. It is shared with the
ESAI SDO0 signal. The pin may be used as SDO0_1 if it is not defined as ESAI SDO0. The
pin may be used as GPIO PE11 if not used by the ESAI or ESAI_1. The ESAI_1 Multiplex
Control Register (EMUXR) defines if the pin belongs to the ESAI or to the ESAI_1.
11.2.2
SERIAL TRANSMIT 1 DATA PIN (SDO1_1)
SDO1_1 transmits data from the TX1_1 serial transmit shift register. It is shared with the
ESAI SDO1 signal. The pin may be used as SDO1_1 if it is not defined as ESAI SDO1. The
pin may be used as GPIO PE10 if not used by the ESAI or ESAI_1. The ESAI_1 Multiplex
Control Register (EMUXR) defines if the pin belongs to the ESAI or to the ESAI_1.
11.2.3
SERIAL TRANSMIT 2/RECEIVE 3 DATA PIN
(SDO2_1/SDI3_1)
SDO2_1/SDI3_1 transmits data from the TX2_1 serial transmit shift register when
programmed as a transmitter pin, or receives serial data to the RX3_1 serial receive shift
register when programmed as a receiver pin. It is shared with the ESAI SDO2/SDI3 signal.
The pin may be used as SDO2_1/SDI3_1 if it is not defined as ESA I SDO2/SDI3. The pin
may be used as GPIO PE9 if not used by the ESAI or ESAI_1. The ESAI_1 Multiplex Control
Register (EMUXR) defines if the pin belongs to the ESAI or to the ESAI_1.
11.2.4
SERIAL TRANSMIT 3/RECEIVE 2 DATA PIN
(SDO3_1/SDI2_1)
SDO3_1/SDI2_1 transmits data from the TX3_1 serial transmit shift register when
programmed as a transmitter pin, or receives serial data to the RX2_1 serial receive shift
register when programmed as a receiver pin. It is shared with the ESAI SDO3/SDI2 signal.
