Section 6 Bus Controller
6.2.6
CSCR is an 8-bit readable/writable register that enables or disables output of chip select signals
(
If output of a chip select signal
corresponding pin functions a chip select signal (
settings. CSCR cannot be modified in single-chip mode.

Read/Write
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.
