This bit is 1, indicating that the bit value (bit 5) of the pin
replacement register is 1. The value of bit 5 of the pin
replacement register, indicating that this bit becomes 0.
This is a read-only bit and it is not affected by writing.

The read value of this bit is always 0 and this bit is not affected
by writing.

(8-bit I/O)
Read/Write
0
The MB86967 enters the word transfer mode (PD0 to PD15).
In this case, bit 5 (SB/SW) of the control register (DLCR6) in
the LAN controller is set to 0.
1
The MB86967 enters the byte transfer mode (PD0 to PD7). In
this case, SB/-SW (bit 5) of DLCR6 in the LAN controller is set
to 1.
The system must set CE2 Non-active.
4 and 3 Not used

—
The read value is always 0. These bits are not affected by
writing.

This bit clears the power-down mode.
When this bit is cleared, bit 5 (STBY) of DLCR7 in the LAN
controller is also cleared to 1.
1
The power-down mode is set.
When this bit is set, bit 5 (STBY) of DLCR7 is set to 0, making
it possible to place the LAN controller and 10BASE-T
transceiver in the standby state. Presetting bit 4 of BMPR14 in
the LAN controller causes the MB86967 to enter the
shutdown mode (oscillation stopped).
This bit should be set after initializing the LAN controller.
Return from the shutdown mode should be made by reset.
See 4. Operation Sequence in PC Card Mode.
1 and 0 Not used
Read
—
The read values of these bits is always 0. These bits are not
affected by writing.
