Description
TDM0_SCSn
TDM1_SCSn
O
CMOS
VDDO_B
or
VDDO_C
SPI chip select0/1
Driven by MV78100 to the SLIC device. Useful when the MV78100
interfaces two SLIC devices and uses two SPI chip select signals
(one to each SLIC device) rather than chaining of the devices.
NOTE: Multiplexed on MPP.

CMOS
VDDO_B
or
VDDO_C
SPI clock
Driven by the MV78100 to the SLIC device.
NOTE: Multiplexed on MPP.
VDDO_B
or
VDDO_C
SPI write data
Driven by the MV78100 to the SLIC device.
NOTE: Multiplexed on MPP.
VDDO_B
or
VDDO_C
SPI read data
Driven by the SLIC device to the MV78100
NOTE: Multiplexed on MPP.
The SLIC device has a dedicated SPI interface for SLIC registers access. This is not the MV78100 SPI
interface listed in Section 2.2.10, SPI Interface Pin Assignment, on page 34.
