MR17: Interrupt Control/Status Register
The Interrupt Control/Status Register provides the means for controlling and observing the events, which
trigger an interrupt on the INTR pin. This register can also be used in a polling mode via the MII Serial
Interface as a means to observe key events within the PHY via one register address. Bits 0 through 7 are
status bits, which are each set to logic one based upon an event. These bits are cleared after the register
is read. Bits 8 through 15 of this register, when set to logic one, enable their corresponding bit in the
lower byte to signal an interrupt on the INTR pin. The assertion level of this interrupt signal output on the
INTR pin can be set via the MR16.14 (INPOL) bit.
