Section 23 Gigabit Ethernet Controller (GETHER)
23.3.3
ECSR is a 32-bit readable/writable register that indicates the status in the E-MAC. This status can
be notified to the CPU by interrupts. When 1 is written to the PFROI, LCHNG, MPD, and ICD
bits, the corresponding flags can be cleared. Writing 0 does not affect the flag. For bits that
generate interrupts, the interrupt can be enabled or disabled by the corresponding bit in ECSIPR.
Writing 1 or 0 to the PHYI bit does not change its value.
The interrupts generated due to this status register are indicated in each ECI bit in EESR of the E-
DMAC0 for port 0 and the E-DMAC1 for port 1.

These bits are always read as 0. The write value should
always be 0.
PAUSE Frame Retransmit Retry Over
Indicates whether the retransmit count for
retransmitting a PAUSE frame when flow control is
enabled has exceeded the retransmit upper-limit set in
the automatic PAUSE frame retransmit count register
(TPAUSER).
0: PAUSE frame retransmit count has not exceeded the
1: PAUSE frame retransmit count has exceeded the
