T7121 HDLC Interface for ISDN (HIFI-64)
Timing Characteristics
(continued)
(CMS = 0, CLKXI = 0, CLKRI = 1, FSPOL = 1, RBM = TBM = 11111111)
5-5049
1.Edge of clock used to sample FS (selected by the FE bit [R0—B6]).
2.Edge of first bit transmission (see Figures 12—20).
3.The CLKXI bit (R9—B4) controls the edge on which data is transmitted, and the CLKRI bit (R9—B0) controls the edge on which received data
is sampled.
