13.6.11 Flexible Filter Value Table
FFVT (09800h - 09BF8h; R/W)
The Flexible Filter Value and Table is used to store the one value for each byte location in a packet
for each flexible filter. If the corresponding mask bit is set to 1b, the Flexible Filter compares the
incoming data byte to the values stored in this table.
Before writing to the Flexible Filter Value Table the driver must first disable the flexible filters by
writing 0b’s to the Flexible Filter Enable bits of the Wakeup Filter Control Register
(WUFC.FLXn).
13.7 Statistics Registers
All statistics registers are implemented as 32-bit registers. 64-bit accesses to these registers must
have the upper byte enables de-asserted. 32-bit registers with addresses not on a quadword
boundary cannot be accessed through a 64-bit access.
Registers that count octets make up 64-bit registers.
