Name
30
DPE
Internal data parity error. This bit indicates that the eTSEC has detected a parity error on its stored data,
which is likely to compromise the validity of recently transferred frames.
0 No parity errors detected.
1 Data held in the FIFO or filer arrays is expected to be corrupted due to a parity error.
31
PERR
Receive frame parse error for TCP/IP off-load. This bit indicates that a received frame could not be parsed
unambiguously, due to encapsulated header type fields contradicting each other.
0 Received frame parsed successfully.
1 Received frame parse revealed header inconsistencies.

Interrupt Mask Register (IMASK)

The interrupt mask register provides control over which possible interrupt events in the IEVENT register
are permitted to participate in generating hardware interrupts to the PIC. All implemented bits in this
register are R/W and cleared upon a hardware reset. If the corresponding bits in both the IEVENT and
IMASK registers are set, the PIC receives an interrupt (for each eTSEC these are grouped into transmit,
receive, and error/diagnostic interrupts). The interrupt signal remains asserted until either the IEVENT bit
is cleared, by writing a 1 to it, or by writing a 0 to the corresponding IMASK bit.
Figure 15-5
describes the IMASK register.
