transfer. RBCLK and TBCLK must be frequency-locked to QCLK, though the
use of two internal FIFOs allow an arbitrary phase relationship to QCLK. TQ[1]
and TQ[0] are sampled on the active edge of TBCLK, as programmed through the
MCI. RQ[1] and RQ[0] are output on the active edge of RBCLK, also as pro-
grammed through the MCI. The clock relationships for the case where TBCLK is
programmed to be falling-edge active and RBCLK is rising-edge active are illus-
trated in Figure 2-8.

Parallel slave mode uses RBCLK and TBCLK inputs to synchronize data
