Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
SSI1 TX on uDMA Ch25. When set, indicates uDMA channel 25 is
available and connected to the transmit path of SSI module 1.
SSI1 RX on uDMA Ch24. When set, indicates uDMA channel 24 is
available and connected to the receive path of SSI module 1.
UART1 TX on uDMA Ch23. When set, indicates uDMA channel 23 is
available and connected to the transmit path of UART module 1.
UART1 RX on uDMA Ch22. When set, indicates uDMA channel 22 is
available and connected to the receive path of UART module 1.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
SSI0 TX on uDMA Ch11. When set, indicates uDMA channel 11 is
available and connected to the transmit path of SSI module 0.
SSI0 RX on uDMA Ch10. When set, indicates uDMA channel 10 is
available and connected to the receive path of SSI module 0.
UART0 TX on uDMA Ch9. When set, indicates uDMA channel 9 is
available and connected to the transmit path of UART module 0.
UART0 RX on uDMA Ch8. When set, indicates uDMA channel 8 is
available and connected to the receive path of UART module 0.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
USB EP3 TX on uDMA Ch5. When set, indicates uDMA channel 5 is
available and connected to the transmit path of USB endpoint 3.
USB EP3 RX on uDMA Ch4. When set, indicates uDMA channel 4 is
available and connected to the receive path of USB endpoint 2.
