This bit, together with the AUTO_EXT_SYNC_EN bit (b7, 09H), determines whether EX_SYNC1 is enabled to synchronize
the frame sync output signals.
This bit determines how to clear the phase lock alarm.
0: The phase lock alarm will be cleared when a ‘1’ is written to the corresponding INn_PH_LOCK_ALARM bit (b4/0,
43H~49H).
1: The phase lock alarm will be cleared after a period ( = TIME_OUT_VALUE[5:0] (b5~0, 08H) X MULTI_FACTOR[1:0]
(b7~6, 08H) in second ) which starts from when the alarm is raised. (default)
These bits set the frequency of the frame sync signal input on the EX_SYNC1 pin.
00: 8 kHz (default)
01: 8 kHz.
10: 4 kHz.
11: 2 kHz.
This bit selects the SDH or SONET network type.
0: SDH. The DPLL required clock is 2.048 MHz when the IN_FREQ[3:0] bits (b3~0, 14H~17H & 19H~22H) are ‘0001’; the
T0/T4 DPLL output from the 16E1/16T1 path is 16E1; and OUT9 outputs a 2.048 MHz signal if enabled.
1: SONET. The DPLL required clock is 1.544 MHz when the IN_FREQ[3:0] bits (b3~0, 14H~17H & 19H~22H) are ‘0001’; the
T0/T4 DPLL output from the 16E1/16T1 path is 16T1; and OUT9 outputs a 1.544 MHz signal if enabled.
The default value of this bit is determined by the SONET/ SDH pin during reset.
This bit is read only. It indicates the value of the MS/ SL pin.
This bit selects Revertive or Non-Revertive switch for T0 path.
0: Non-Revertive switch. (default)
1: Revertive switch.
Its default value is determined by the MS/ SL pin during reset.
