Bit Bit Name Initial Value R/W Description
3 SDE 0 R/W Shutdown Enable
0: Host interface pin shutdown function disabled
1: Host interface pin shutdown function enabled
When the shutdown function is enabled, host interface
pin functions can be halted, and the pins placed in the
high-impedance state, according to the state of the
HIFSD pin.
2 CS4E 0 R/W CS4 Enable
0: Channel 4 functions disabled
1: Channel 4 functions enabled (channel 4 pin is
enabled)
Enabling setting is valid when the HI12E bit is 1.
1 CS3E 0 R/W CS3 Enable
0: Channel 3 functions disabled
1: Channel 3 functions enabled (channel 3 pin is
enabled)
Enabling setting is valid when the HI12E bit is 1.
0 HI12E 0 R/W Host Interface Enable Bit
0: Host interface functions are disabled
1: Host interface functions are enabled (settings of bits
CS2E to CS4E, FGA20E, and SDE are enabled)
Enabling setting is valid in single-chip mode.
