CSCR is an 8-bit readable/writable register that enables or disables output of chip select signals
(CS
If a chip select signal (CS
functions as a chip select signal (CS
functions. CSCR cannot be modified in single-chip mode.
CSCR is initialized to H'0F by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Bits 7 to 4—Chip Select 7 to 4 Enable (CS7E to CS4E): These bits enable or disable output of
the corresponding chip select signal.
Bit n: CSnE
0
1
Note: n = 7 to 4
Bits 3 to 0—Reserved: Read-only bits, always read as 1.
