• Manufacturer Part Number: h8s-2646
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2600 Series
• Manufacturer: Renesas Electronics Corporation.

Bit 2—Smart Card Data Invert (SINV): Specifies inversion of the data logic level. The SINV
bit does not affect the logic level of the parity bit(s): parity bit inversion requires inversion of the
O/E bit in SMR.
Bit 1—Reserved: It is always read as 1 and cannot be modified.
Bit 0—Smart Card Interface Mode Select (SMIF): When the smart card interface operates as a
normal SCI, 0 should be written in this bit.
13.2.10 Module Stop Control Register B (MSTPCRB)
MSTPCRB is an 8-bit readable/writable register that perform module stop mode control.
Setting any of bits MSTPB7 and MSTPB6 to 1 stops SCI0 and SCI1 operating and enter module
stop mode on completion of the bus cycle. For details, see section 22.5, Module Stop Mode.
MSTPCRB is initialized to H'FF by a reset and in hardware standby mode. They are not
initialized in software standby mode.
