Error Mask Registers
2-13
EXCCOL
Excessive Collision Port x Error
A one on any of the bits in this field indicates that the
frame could not be transmitted after 16 attempts for the
specific port. The L64381 aborts the transmission with no
further retries.
[7:4]
LINKFL
Link Failure Port x Error
A one on any of the bits in this field indicates that a Link
Failure error (either no data or link integrity pulses were
received for 100 ms) occurred for the specific port.
[3:0]
2.5
Error Mask
Registers
The two Error Mask Registers contain the mask bits for the error fields
in the corresponding Error Registers. When a bit is set to one in the
Mask Register, the corresponding error is masked and the L64381 does
not assert the INTERRUPT signal for that error condition.
2.5.1
Error Mask
Register 0
Figure 2.8 shows Error Mask Register 0. This register contains the mask
bits for the error fields in Error Register 0. Upon power-up or when
RESET is asserted, all bits in this register are zeros.
Figure 2.8
Error Mask Register 0
INT
Enable Interrupts
When this bit is a one, the L64381 generates an interrupt
whenever a bit in the Error Register is written to a one,
provided that the bit’s corresponding mask bit is not set
in the Error Mask Register.
15
PINTM
Processor Interface Error Mask
A one on this bit masks the Processor Interface error.
14
R
Reserved
This bit is reserved and reads as zero.
13
BINTM
Bus Interface Error Mask
A one on this bit masks the Bus Interface error.
