Power Control register (address R = 3Dh to 3Fh, W = 3Dh, S = 3Eh, C = 3Fh) bit description
10.2 Extended register set
Addresses 00h to 3Fh of the extended register set directly map to the immediate set. This
means a read, write, set or clear operation to these extended addresses will operate on
the immediate register set.
Addresses 40h to FFh are not implemented. Operating on these addresses will have no
effect on the PHY.
Description
reserved; the link must never write logic 1 to these bits.
BValid Fall: Enables RXCMDs for HIGH-to-LOW transitions on BVALID. When BVALID
changes from HIGH to LOW, the ISP1504 will send an RXCMD to the link with the ALT_INT bit
set to logic 1.
This bit is optional and is not necessary for OTG devices. The session valid comparator should
be used instead.
BValid Rise: Enables RXCMDs for LOW-to-HIGH transitions on BVALID. When BVALID
changes from LOW to HIGH, the ISP1504 will send an RXCMD to the link with the ALT_INT bit
set to logic 1.
This bit is optional and is not necessary for OTG devices. The session valid comparator should
be used instead.
reserved; the link must never write logic 1 to this bit.
