REGISTERS
Register Overview
The following tables summarize the configuration and I/O
registers of the ProMedia.
These tables also document the
power-on default value (“Default”) and access type (“Acc”)
for each register.
Access type definitions used are RW
(Read/Write), RO (Read/Only), “—” for reserved / used
(essentially the same as RO), and RWC (or just WC) (Read /
Write 1’s to Clear individual bits). Registers indicated as RW
may have some read/only bits that always read back a fixed
value (usually 0 if unused); registers designated as RWC or
WC may have some read-only or read write bits (see
individual register descriptions following these tables for
details).
All offset and default values are shown
in
hexadecimal unless otherwise indicated.
