corresponds to a bit in the Interrupt Register2 (IR2). If an interrupt mask bit is set, an
interrupt will be issued whenever the corresponding bit in the IR2 is set. If the bit of IMR is
set as ‘0’, corresponding interrupt will not be triggered by the enabled bit in the IR2.

IMR (Interrupt Mask Register) [R/W] [0xFE0016] [0x00]
The Interrupt Mask Register is used for masking interrupts. Each interrupt mask bit
RTR (Retry Time-period Register) [R/W] [0xFE0017 – 0xFE0018] [0x07D0]
This register sets the period of timeout. Value 1 means 100us. The default timeout is 200ms
Re-transmission will occur if there is no response or response is delayed from the remote

destination IP address is transmitted during a UDP data transmission. The
UNREACH bit will be set as ‘1’. This bit can be cleared to ‘0’ by writing ‘1’
to this bit.
PPPoE Connection Close
In the PPPoE Mode, ‘1’ is set if the PPPoE connection is closed. This bit can
be cleared to ‘0’ by writing ‘1’ to this bit.
