STF_THRESH_C[9:8]
STF_THRESH_C[8:0] Bit Stuffing Threshold C—Contains the number of GCLK cycles equal to 24 HDSL bit times.
If the phase measured from PCM to HDSL 6 ms frames is a positive value less than
STF_THRESH_C, then 4 STUFF bits are inserted in the outgoing frame. If the phase is a
positive value greater than or equal to STF_THRESH_C, then the phase tolerance on HDSL,
PCM, or GCLK inputs is exceeded and the STUFF generator reports STUFF_ERR
[STATUS_3; addr 0x07].
NOTE: STF_THRESH_C must be greater than STF_THRESH_B by a value of 4 HDSL bit
times (4 x HDSL ÷ GCLK) but not greater than a value of 0x3FF.
