Cypress CY7C67200 manual SPI Transmit Address Register 0xC0D8 R/W

CY7C67200

Data Ready bit of the SPI Control register is set to ‘1’. Writing to this register in PIO byte mode will initiate a transfer of data, the number of bits defined by Transmit Bit Length field in the SPI Control register.

Data (Bits [7:0])

The Data field contains data received or to be transmitted on the SPI port.

Reserved

All reserved bits must be written as ‘0’.
