OHP Registers
Table 76. Registers 0x0416—0x0419: Toggles (R/W)
Reset default of registers = 0x0000.
Note: These registers are one-shot type registers. They are enabled by writing a 0-to-1 transition to a bit. After
Table 77. Registers 0x041A, 0x041C, 0x041E, 0x0420: Continuous N Times Detect (CNTD) Values (R/W)
Reset default of registers = 0x3333.

Reserved. These bits must be written to their
reset default value (00000000000).
Transmit A1/A2 Error Enable. Enable signal to
start the insertion of A2 errors in the outgoing
frame. The number of consecutive errors is
controlled by TA1A2ERRINS[4:0].
TA1A2ERREN[A] is valid in STS-48/STM-16
mode.
Signal Fail Clear. Allows the signal fail algo-
rithm to be forced into the normal state.
Signal Fail Set. Allows the signal fail algorithm
to be forced into the failed state.
Signal Degrade Clear. Allows the signal
degrade algorithm to be forced into the normal
state.
Signal Degrade Set. Allows the signal degrade
algorithm to be forced into the degraded state.
Continuous N Times Detect for K2[2:0] Byte.
The valid range for these bits is 0x2—0xF.
Invalid values will be mapped to a value of 0x1.
In STS-48/STM-16 mode, CNTDK2[A] is valid.
Continuous N Times Detect for APS (K1,
K2[7:3]) Byte. The valid range for these bits is
0x2—0xF. Invalid values will be mapped to a
value of 0x1. In STS-48/STM-16 mode,
CNTDK1K2[A] is valid.
Continuous N Times Detect for F1 Byte. The
valid range for these bits is 0x2—0xF. Invalid
values will be mapped to a value of 0x1. In
STS-48/STM-16 mode, CNTDF1[A] is valid.
Continuous N Times Detect for J0Z0 Bytes.
The valid range for these bits is 0x2—0xF.
Invalid values will be mapped to a value of 0x1.
In STS-48/STM-16 mode, CNTDJ0Z0[A] is
valid.
