[7:0]
ACR Prescaler and Divider
This register is made up of the ACR [7:5] Prescaler field and the ACR
[4:0] Divider field. The values in these fields configure the auxiliary
clock function, the prescalar value, the clock signal frequency.
The frequency range is given for f
VCO
= 400 MHz.

In the LF generator, the programmable division factor is
32 + ACR[4:0]. In the HF generator, it is simply ACR[4:0]. This allows
the building of any frequency from 24 Hz to 1.1 kHz (within ±1.5%) in
the full operating range. The output signal is square in all cases.
When the auxiliary register is written, the prescaler and the program-
mable divider are reset.

[7:0]
The actual frequency is f
VCO
/(128 R[7:0]). When this register is
accessed, the divider by 16 (also common to AUX_CLK) and the
divider by R[7:0] are initialized.
