VDDO_B
or
VDDO_C
SPI chip select0/1
Driven by MV78200 to the SLIC device. Useful when the MV78200
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.
TDM_SCLK
O
CMOS
VDDO_B
or
VDDO_C
SPI clock
Driven by the MV78200 to the SLIC device.
NOTE: Multiplexed on MPP.
TDM_SMOSI
O
CMOS
VDDO_B
or
VDDO_C
SPI write data
Driven by the MV78200 to the SLIC device.
NOTE: Multiplexed on MPP.
TDM_SMISO
I
CMOS
VDDO_B SPI read data
or
Driven by the SLIC device to the MV78200
VDDO_C NOTE: Multiplexed on MPP.
Note
The SLIC device has a dedicated SPI interface for SLIC registers access. This is not the MV78200 SPI
interface listed in Section 2.2.10, SPI Interface Pin Assignment, on page 36.
