71M6521DE/DH/FE Data Sheet
Figure 16 summarizes the timing relationships between the input MUX states, the CE_BUSY signal, and the two
serial output streams. In this example, MUX_DIV=4 and FIR_LEN=1 (384). The duration of each MUX frame is 1 +
MUX_DIV * 2 if FIR_LEN=288, and 1 + MUX_DIV * 3 if FIR_LEN=384. An ADC conversion will always consume an
integer number of CK32 clocks. Followed by the conversions is a single CK32 cycle where the bandgap voltage is
allowed to recover from the change in CROSS.
Each CE program pass begins when ADC0 (channel IA) conversion begins. Depending on the length of the CE
program, it may continue running until the end of the ADC3 (VB) conversion. CE opcodes are constructed to ensure
that all CE code passes consume exactly the same number of cycles. The result of each ADC conversion is inserted
into the CE DRAM when the conversion is complete. The CE code is written to tolerate sudden changes in ADC data.
The exact CK count when each ADC value is loaded into DRAM is shown in Figure 16.
Figure 16 also shows that the serial RTM data stream begins transmitting at the beginning of state ‘S.’ RTM,
consisting of 140 CK cycles, will always finish before the next code pass starts.
