TDZC:
Selects the TZC signal for generating the TRKCNCL signal during brake circuit operation.
TDZC = 0: The edge of the HPTZC or STZC signal, whichever has the faster phase, is used.
TDZC = 1: The edge of the HPTZC or STZC signal or the tracking drive signal zero-cross,
whichever has the fastest phase, is used. (See § 5-12.)
DTZC:
DTZC delay (8.5/4.25µs, when MCK = 128Fs)
Default value: 0 (4.25µs)
