DS3/E3 FRAMER IC
XRT7250
REV. 1.1.1
105
This Reset-upon-Read register, along with the PMON
LCV Event Count Register - LSB (Address = 0x50)
contains a 16-bit representation of the number of Line
Code Violations that have been detected by the Re-
ceive E3 Framer, since the last read of these regis-
ters. This register contains the LSB (or Lower-Byte)
value of this 16 bit expression.
2.3.8.3
PMON Framing Bit/Byte Error Count
Register - MSB
This Reset-upon-Read register, along with the PMON
Framing Bit/Byte Error Count Register - LSB (Ad-
dress = 0x53) contains a 16-bit representation of the
number of Framing Bit or Byte Errors that have been
detected by the Receive DS3/E3 Framer, since the
last read of these registers. This register contains the
MSB (or Upper-Byte) value of this 16 bit expression.
2.3.8.4
PMON Framing Bit/Byte Error Count
Register - LSB
This Reset-upon-Read register, along with the PMON
Framing Bit/Byte Error Count Register - MSB (Ad-
dress = 0x52) contains a 16-bit representation of the
number of Framing Bit or Byte Errors that have been
detected by the Receive DS3/E3 Framer, since the
last read of these registers. This register contains the
LSB (or Lower-Byte) value of this 16 bit expression.
2.3.8.5
PMON Parity Error Count Register -
MSB
This Reset-upon-Read register, along with the PMON
Parity Error Count Register - LSB (Address = 0x55)
contains a 16-bit representation of the number of P-
