Detailed Description

Specification of the Rx Address Selector Control Register.

The Rx Address Selector Control Register is used to configure which Rx Address bits select the Secure, PrivID and Segment/Length value arrays. This register also holds the secure value when the secure selection is one or zero.

Field Documentation

[rw] The RX address bits to use as PrivID lookup

Field size: 4 bits

The PrivID index is extracted from the specified incoming address bits. The index is then looked up in the table defined through hyplnkRXPrivIDIdxReg_s and hyplnkRXPrivIDValReg_s

This is the inverse of hyplnkTXAddrOvlyReg_s::txPrivIDOvl

Value of secure signal when bit referenced by rxSecSel is 1.

Field size: 1 bit

Value of secure signal when bit referenced by rxSecSel is 0.

Field size: 1 bit

Select RX address bit used as Secure bit.

Field size: 4 bits

This is the inverse of hyplnkTXAddrOvlyReg_s::txSecOvl

The secure signal is determined by selecting the bit specified by rxSecSel from the incoming address, then deciding the signal value by apply rxSecHi when that address bit is 1, or rxSecLo when that address bit is 0.

[rw] Segment and Offset Selector

Field size: 4 bits

The segment number and offset are extracted from the incoming address as specified in the following table.

The segment number is then looked up in hyplnkRXSegValReg_s

This is the inverse of hyplnkTXAddrOvlyReg_s::txIgnMask
