QuickPoll Status Register (register 17)
The QuickPoll status register is a 16-bit read only register
used to indicate the comprehensive status of the
ICS1889
. All
register status bits that might need to be repetitively examined
at run time are located in this register, even though some bits
duplicate functionality from other registers. This allows the
device status to be rapidly obtained with a single register
access.
The register is accessed via the management interface of the
MII. It can always be read and may be written by setting the
override bit in the Configuration Register (register 16, bit 15)
and then performing a write operation. It is initialized during a
power-up or reset to predefined default values.
