16.10.36 Shared Bus Control Register (SHARED_BUS)—Offset E0h
This register is optional. The devices on shared bus are not intended to be controlled by
the Standard Host Driver. This is because shared bus configuration depends on a host
system; the devices on shared bus may be controlled by a specific driver of a host
system.

Back-End Power Control (pwr_ctrl):
Each bit of this field controls back-end power
supply for an embedded device. Host interface voltage (VDDH) is not controlled by this
field. The number of devices supported is specified by Number of Clock Pins, and a
maximum of 7 devices can be controlled.
•
•
D24 Back-end Power Control for Device 1
•
D25 Back-end Power Control for Device 2
•
D26 Back-end Power Control for Device 3
•
D27 Back-end Power Control for Device 4
•
D28 Back-end Power Control for Device 5
•
D29 Back-end Power Control for Device 6
•
D30 Back-end Power Control for Device 7
The function of each bit is defined as follows:
•
•
0 = Back-end Power is Off
•
1 = Back-end Power is Supplied
Back-End power control is effective for embedded memory devices in the Sleep State
that support the Sleep command (CMD14) to reduce power consumption and embedded
SDIO devices when IOEx is set to 0.
