QADC64E Legacy Mode Operation
The MCU IMB3 clock frequency is the basis of the QADC64E timing. The QADC64E requires that the
IMB3 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 IMB3
clock cycles in the high phase of the QCLK wave. The 3-bit PSL field selects the number of IMB3 clock
cycles in the low phase of the QCLK wave.
Example 1 in
IMB3 clock and with PSL = 7 the QCLK remains low for 8 IMB3 clock cycles. Example 2 shows that
when PSH = 11, QCLK is high for 12 IMB3 clock cycles and with PSL = 7, QCLK is low for 8 IMB3
clock cycles. Finally, example 3 shows that with PSH = 7 and PSL = 7, QCLK alternates between high and
low every 8 IMB3 cycles.
