ICS1890
QuickPoll Detailed Status Register (register 17 [0x11])
QuickPoll Detailed Status (register 17)
The ICS1890 detailed status register is a 16-bit read-only
register used to indicate detailed status of the ICS1890. It is
accessed via the management interface of the MII. It is initialized
during a power-up or reset to pre-defined default values. A
number of bits are duplicated in this register from others to
make them more easily accessable when polling the device for
status. This should be the only register that needs to be
repeatedly polled in an application.
Data Rate (bit 15)
If set to a logic one, this bit indicates that has been selected
100 Mbps mode. If set to a logic zero, it indicates that the
initial-10 Mbps mode has been selected. This bits setting
depends on the setting of the HW/SW pin, 10/100SEL pin,
ANSEL pin, and the setting of bits 0:12, 0:13, and 1:5.
