The AN983B provides 2 kinds of LED display mode; the detail descriptions about the operation are
described in the PIN Description section.
There are two ways to reset the AN983B. First, hardware reset, the AN983B can be reset via RST#
pin. For ensuring proper reset operation, at least 100µs active Reset input signal is required. Second,
software reset, when bit 0 of CSR0 register is set to 1, the AN983B will reset entire circuits and
register to default value then clear the bit 0 of CSR0 to 0.
When bit 15 of PHY register 0 is set to 1, the transceiver will reset entire circuits and register
100Mbps(on) or 10Mbps(off)
