Note 1a: The acc (access) column indicates how the SPI master can access the register.

R = read, RC = read or clear, RSC = read, set, or clear.

Writing to an R register (read only) has no effect.

Writing a 1 to an RC bit (read or clear) clears the bit.

Writing a zero to an RC bit has no effect.
