• Bit 6 - WRCOL: Write Collision Flag
The WRCOL bit is set if the DATA register is written during a data transfer. The WRCOL bit is
cleared by first reading the STATUS register with WRCOL set, and then accessing the DATA
register.
• Bit 5:0 - Reserved
These bits are reserved and will always be read as zero. For compatibility with future devices,
always write these bits to zero when this register is written.
The DATA register used for sending and receiving data. Writing to the register initiates the data
transmission, and the byte written to the register will be shifted out on the SPI output line. Read-
ing the register causes the Shift Register Receive buffer to be read, and return the last bytes
successfully received.
