Shift Control Register
| SDIR | Shift Direction 0 (value1): Shift LSB first 1 (value2): Shift MSB first |
| PDL | Passive Data Level 0 (value1): The passive data level is 0. 1 (value2): The passive data level is 1. |
| DSM | Data Shift Mode 0 (value1): Receive and transmit data is shifted in and out one bit at a time 2 (value3): Receive and transmit data is shifted in and out two bits at a time 3 (value4): Receive and transmit data is shifted in and out four bits at a time |
| HPCDIR | Port Control Direction 0 (value1): The pin(s) with hardware pin control enabled are selected to be in input mode. 1 (value2): The pin(s) with hardware pin control enabled are selected to be in output mode. |
| DOCFG | Data Output Configuration 0 (value1): DOUTx = shift data value 1 (value2): DOUTx = inverted shift data value |
| TRM | Transmission Mode 0 (value1): The shift control signal is inactive 1 (value2): The shift control signal is active at 1-level 2 (value3): The shift control signal is active at 0-level 3 (value4): The shift control signal is always active |
| FLE | Frame Length |
| WLE | Word Length 0 (value1): The data word contains 1 data bit located at bit position 0. 1 (value2): The data word contains 2 data bits located at bit positions [1:0]. 14 (value3): The data word contains 15 data bits located at bit positions [14:0]. 15 (value4): The data word contains 16 data bits located at bit positions [15:0]. |
