5.6.2 SWC Registers
The SWC registers are organized in two banks. The offsets
are related to a base address that is determined by the
SWC Base Address Register in the logical device configu-
ration. The lower three registers are common to the two
banks while the upper registers (03h-0Fh) are divided as
follows:
• Bank 0 holds reserved registers.
• Bank 1 holds the CEIR Control Registers.
The active bank is selected through the Configuration Bank
Select field (bits [1:0]) in the Wakeup Configuration Regis-
ter (WKCFG). See Table 5-29 on page 118.
The tables that follow provide register maps and bit defini-
tions for Banks 0 and 1.
