10.2 Extended register set

Addresses 30h to 3Fh contain vendor-specific registers.
This register controls various aspects of the ISP1507. See
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 may result in
undefined behavior of 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 ISP1507 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. This bit is provided for debugging
purposes. 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 ISP1507 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. This bit is provided for debugging
purposes. The session valid comparator should be used instead.
