29, D(1:0). Additionally a general purpose clock can be driven out on either GPIO, DOUT or MISO pin.
This clock can be a divided down version of CDIV_CLKIN. The value of this clock divider can be
programmed from 1 to 128 by writing to Page 0, Register 26, D(6:0). The CDIV_CLKIN can itself be
programmed as one of the clocks among the list shown in Figure 5-42. This can be controlled by
programming the mux in Page 0, Register 25, D(2:0).
