Type Aliases

LBM_R

Field LBM reader - Loop back mode: 0 Normal serial port operation enabled. 1 Output of transmit serial shifter is connected to input of receive serial shifter internally.

LBM_W

Field LBM writer - Loop back mode: 0 Normal serial port operation enabled. 1 Output of transmit serial shifter is connected to input of receive serial shifter internally.

MS_R

Field MS reader - Master or slave mode select. This bit can be modified only when the PrimeCell SSP is disabled, SSE=0: 0 Device configured as master, default. 1 Device configured as slave.

MS_W

Field MS writer - Master or slave mode select. This bit can be modified only when the PrimeCell SSP is disabled, SSE=0: 0 Device configured as master, default. 1 Device configured as slave.

R

Register SSPCR1 reader

SOD_R

Field SOD reader - Slave-mode output disable. This bit is relevant only in the slave mode, MS=1. In multiple-slave systems, it is possible for an PrimeCell SSP master to broadcast a message to all slaves in the system while ensuring that only one slave drives data onto its serial output line. In such systems the RXD lines from multiple slaves could be tied together. To operate in such systems, the SOD bit can be set if the PrimeCell SSP slave is not supposed to drive the SSPTXD line: 0 SSP can drive the SSPTXD output in slave mode. 1 SSP must not drive the SSPTXD output in slave mode.

SOD_W

Field SOD writer - Slave-mode output disable. This bit is relevant only in the slave mode, MS=1. In multiple-slave systems, it is possible for an PrimeCell SSP master to broadcast a message to all slaves in the system while ensuring that only one slave drives data onto its serial output line. In such systems the RXD lines from multiple slaves could be tied together. To operate in such systems, the SOD bit can be set if the PrimeCell SSP slave is not supposed to drive the SSPTXD line: 0 SSP can drive the SSPTXD output in slave mode. 1 SSP must not drive the SSPTXD output in slave mode.

SSE_R

Field SSE reader - Synchronous serial port enable: 0 SSP operation disabled. 1 SSP operation enabled.

SSE_W

Field SSE writer - Synchronous serial port enable: 0 SSP operation disabled. 1 SSP operation enabled.

W

Register SSPCR1 writer
