18.2.7
MSTPCR, comprising two 8-bit readable/writable registers, performs module stop mode control.
When the MSTP2 bit is set to 1, the host interface halts and enters module stop mode. See section
25.5, Module Stop Mode, for details.
MSTPCR is initialized to H'3FFF by a reset and in hardware standby mode. It is not initialized in
software standby mode.
MSTPCRL Bit 2—Module Stop (MSTP2): Specifies host interface module stop mode.
18.3
18.3.1
The HIF (slave mode) is activated by setting the HI12E bit (bit 0) in SYSCR2 to 1 in single-chip
mode. When the HIF (slave mode) is activated, all related I/O ports (data port 3, control ports 8
and 9, and host interrupt request port 4) become dedicated host interface ports. Setting the CS3E
bit and CS4E bit to 1 enables the number of HIF channels to be extended to a four, and makes the
channel 3 and 4 related I/O port (part of port B for control and host interrupt requests) a dedicated
host interface port.
Table 18.4 shows HIF host interface channel selection and pin operation.
