The MSWC registers are organized in four banks, all of which are battery-backed. The offsets are related to a base address
that is determined by the MSWC Base Address register in the device configuration registers. The lower 19 offsets are com-
mon to the four banks; the upper offsets (13
The active bank is selected through the Configuration Bank Select field (bits 1-0) in the Wake-Up Configuration register
(WK_CFG).
As a programing aid, the registers are described in this chapter according to the following functional groupings:
For a summary of the abbreviations used for Register Type, see “Register Abbreviations and Access” on page 34.
MSWC Host Register Map
The following tables list the MSWC host registers. For the MSWC core register map, see Section 5.5.6 on page 328.
Wake-Up Event Status Register 0 (WK_STS0)
This register is set to 00
events, associated with the register, have occurred. Writing 1 to a bit clears it to 0. Writing 0 has no effect. Bit 6 behaves in
a special way, as described in the table below.
