9. FUNCTION REGISTERS
W89C841F implements two types of function registers: Cxx and Dxx. Cxx function registers are used
to perform the function control and status monitor of W89C841F. Dxx function registers are used to
control power management parameters, monitor power management status and setup wake-up
frames parameters. The general attributes of W89C841F function registers are described as the
following:
1) The function registers of W89C841F can be mapped into the host I/O space or memory
space.
2) The registers of the W89C841F are double word aligned. Each register consists of 32 bits and
may be accessed using any byte-enable combinations with double word aligned address.
3) Burst access to the registers of W89C841F will be terminated after 1st data transfer
completed with a Disconnect without Data.
4) SoftReset will have the same effect as done by HardReset on the registers of W89C841F,
except for the function registers C34/CMA0, C38/CMA1, D00/DWUPC
D6c/DBWF4BM3,
Dcc/DPA0, Dd0/DPA1 and Df0/DFER
Dfc/DFFER and configuration registers
5) Any read on the reserved register will be returned with 0 value.
