• Manufacturer Part Number: HD6435348R
• Description: Single-Chip Microcomputer
• Manufacturer: Hitachi Semiconductor

SYSCR2 controls the functions of port 6 and the functions of some pins in port 9.
SYSCR2 is initialized to H'80 by a reset and in the hardware standby mode. It is not initialized in
the software standby mode.
Bit 7—Reserved: This bit cannot be modified and is always read as 1.
