Hello,

we use the ti code for the LLC_HB.

There is an PMBUS_CMD 0xF2 (Status_bit_mask) and I don't find a description.

Could you explain these bit, please!

#define STATUS_BIT_MASK {0x00, 0x00, 0x00, 0x80, 0x00, 0x80, 0x80, 0x34, 0xC8, 0x00, 0x00}

Thanks a lot...

PMBUS_CMD 0xF2 (Status_bit_mask) defines what PMBus status registers the device supports.
Not all the different status bytes and bits defined by PMBus are supported by the EVM.
By sending this command the HOST will know which status bits are supported.
