Section 17 Host Interface [H8S/2138 Group]
17.2.2
SYSCR2 is an 8-bit readable/writable register which controls chip operations. Host interface
functions are enabled or disabled by the HI12E bit in SYSCR2. SYSCR2 is initialized to H'00 by a
reset and in hardware standby mode.
Bits 7 and 6—Key Wakeup Level 1 and 0 (KWUL1, KWUL0): The port 6 input level can be
set and changed by software. For details see section 8, I/O Ports.
Bit 5—Port 6 Input Pull-Up Extra (P6PUE): Controls and selects the current specification for
the port 6 MOS input pull-up function connected by means of KMPCR settings. For details see
section 8, I/O Ports.
Bit 4—Reserved: Do not write 1 to this bit.
Bit 3—Shutdown Enable (SDE): Enables or disables the host interface pin shutdown function.
When this 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.

Bit 2—CS4 Enable (CS4E): Reserved. Do not write 1 to this bit.
Bit 1—CS3 Enable (CS3E): Reserved. Do not write 1 to this bit.
Bit 0—Host Interface Enable Bit (HI12E): Enables or disables host interface functions in
single-chip mode. When the host interface functions are enabled, slave mode is entered and
processing is performed for data transfer between the slave and host.
