1 _{The CSC and PCR registers are shown in this table as part of the Nexus programmer’s model. They are only}
present at the top level Nexus controller in a multi-Nexus implementation, not in the Nexus 3 module. The CSC
Register is readable through Nexus, but the PCR is shown for reference only here.
31.11.1 NZ7C3 Register Access via JTAG / OnCE
Access to Nexus3 register resources is enabled by loading a single instruction
(ACCESS_AUX_TAP_ONCE) into the JTAGC instruction register (IR), and then loading the
corresponding OnCE OCMD register with the NEXUS3_ACCESS instruction (see Table 31-5). For the
NZ7C3 module, the OCMD value is 0b00_0111_1100.
