version in a queue. For other MCU IMB clock frequencies and other input sample
times, the same calculations can be made.
The MCU IMB clock frequency is the basis of the QADC64 timing. The QADC64 re-
quires that the IMB clock frequency be at least twice the QCLK frequency. The QCLK
frequency is established by the combination of the PSH and PSL parameters in
QACR0. The 5-bit PSH field selects the number of IMB clock cycles in the high phase
of the QCLK wave. The 3-bit PSL field selects the number of IMB clock cycles in the
low phase of the QCLK wave.

low for eight IMB clock cycles. In Example 2, PSH = 7, the QCLK remains high for eight
