One-Second Yellow Alarm Rule Enforcement
This bit is used to enforce the one-second yellow alarm rule according to the yel-
low alarm (RAI) transmission duration per the ANSI standards.
If the one second alarm rule is enforced, the following will happen:
1.
RAI will be transmitted for at least one second for both ESF and SF.
2.
There must be a minimum of one second delay between termination
of the first RAI and the initiation of a subsequent RAI.
3.
ALARM_ENB bit (see description of bit 6 of this register) controls the
duration of RAI.
4.
YEL[0] & YEL[1] (see description of bits 5-4 of this register) controls the
format of RAI.
If the one second alarm rule is NOT enforced, the following will happen:
1.
RAI will be transmitted for at least one second for ESF and SF.
2.
Minimum one second delay between termination of the first RAI and the
initiation of the subsequent RAI is NOT enforced.
3.
YEL[0] and YEL[1] bits (see description of bits 5-4 of this register) are used
to control the duration AND the format of RAI transmission.
0 - The one-second yellow alarm rule is NOT enforced.
1 - The one-second yellow alarm rule is enforced.
N
OTE
:
When setting this bit to ‘0’, yellow alarm transmission will be backward
compatible with the XRT86L38 device. XRT86L38 does not support the
one-second yellow alarm rule.

Yellow Alarm Transmission Enable
This bit is used to control the duration of yellow alarm (RAI) when the one-second
yellow alarm rule is enforced (bit 7 of this register set to’1’).
When the one-second yellow alarm rule is not enforced (bit 7 of this register set
to’0’), the duration of the RAI is controlled by the YEL[0] and YEL[1] bits (bits 5-4
of this register).
If the one-second alarm rule is enforced:
0 - Stop the transmission of yellow alarm (see description of bits 5-4).
1 - Start the transmission of yellow alarm (see description of bits 5-4).
N
OTE
:
This bit has no function if the one second alarm rule is not enforced.
