Description

SPI Delay register

Fields

PRE_DELAY

Controls the amount of time between SSEL assertion and the beginning of a data transfer. There is always one SPI clock time between SSEL assertion and the first clock edge. This is not considered part of the pre-delay. 0x0 = No additional time is inserted. 0x1 = 1 SPI clock time is inserted. 0x2 = 2 SPI clock times are inserted. … 0xF = 15 SPI clock times are inserted.

POST_DELAY

Controls the amount of time between the end of a data transfer and SSEL deassertion. 0x0 = No additional time is inserted. 0x1 = 1 SPI clock time is inserted. 0x2 = 2 SPI clock times are inserted. … 0xF = 15 SPI clock times are inserted.

FRAME_DELAY

If the EOF flag is set, controls the minimum amount of time between the current frame and the next frame (or SSEL deassertion if EOT). 0x0 = No additional time is inserted. 0x1 = 1 SPI clock time is inserted. 0x2 = 2 SPI clock times are inserted. … 0xF = 15 SPI clock times are inserted.

TRANSFER_DELAY

Controls the minimum amount of time that the SSEL is deasserted between transfers. 0x0 = The minimum time that SSEL is deasserted is 1 SPI clock time. (Zero added time.) 0x1 = The minimum time that SSEL is deasserted is 2 SPI clock times. 0x2 = The minimum time that SSEL is deasserted is 3 SPI clock times. … 0xF = The minimum time that SSEL is deasserted is 16 SPI clock times.

RESERVED

Reserved. Read value is undefined, only zero should be written.
