A1onG:
I2S Audio Port 1 on GPIO.
1 - I2S Port 1 pins are mapped to EGPIO. SDI1 is on
EGPIO[5], SDO1 is on EGPIO[4].
0 - EGPIO[5:4] are not used.
A2onG:
I2S Audio Port 2 on GPIO.
1 - I2S Port 2 pins are mapped to EGPIO. SDI2 is on
EGPIO[13], SDO2 is on EGPIO[6].
0 - EGPIO[13] and EGPIO[6] are not used.
CPENA:
Co-processor Enable.
1 - MaverickCrunch co-processor is enabled.
0 - C o -proc e sso r i s disabled and w ill not a ccept
instructions.
U3EN:
UART3 Enable.
1 - UART3 baud rate clock is active.
0 - UART3 clock is off.
MonG:
Modem on GPIO.
1 - Modem support signals use EGPIO[0] pins.
0 - Modem support signals do not use EGPIO[0] pins
TonG:
TENn on GPIO. This bit has no effect unless HC3EN and
HC1EN are 0.
1 - UART3 TENn signal drives EGPIO[3].
0 - EGPIO[3] used by GPIO.
GonK:
GPIO on Key Matrix.
1 - Key Matrix pins are configured for GPIO operation,
0 - Key Matrix pins are controlled by other options.
The GonK has precedence over the Key Matrix controller.
The SPI0, when m apped to Key Matr ix pins, has
precedence over GPIO. When the Key Matrix pins are
configured for SPI0, the pins unused by SPI0 can be used
for GPIO.
IonU2:
IrDA on UART2.
1 - UART2 is used as an IrDA interface,
0 - UART2 is a normal UART.
D0onG:
External DMA0 hardware handshake signals mapped to
EGPIO pins.
1 - Signals mapped.
0 - Signals not supported.
D1onG:
External DMA1 hardware handshake signals mapped to
EGPIO pins.
1 - Signals mapped.
0 - Signals not supported.
