6.2.6 Chip Select Control Register (CSCR)
CSCR is an 8-bit readable/writable register that enables or disables output of chip select signals
(CS₇ to CS₄).
If output of a chip select signal is enabled by a setting in this register, the corresponding pin
functions a chip select signal (CS₇ to CS₄) output regardless of any other settings.
