System Control Register 2 (SYSCR2) (H8S/2148 Group and H8S/2147N Only)
SYSCR2 is an 8-bit readable/writable register that controls port 6 input level selection and the
operation of host interface functions.
Only bits 7, 6, and 5 are described here. See section 18.2.2, System Control Register 2 (SYSCR2),
for information on bits 4 to 0.
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 setting
can be changed by software, using these bits. The setting of these bits also changes the input level
of the pin functions multiplexed with port 6.
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.
