5.3
ALIS operates with a typical master clock frequency of 16.384 MHz. This clock can either
be supplied from an external source or generated with a crystal by ALIS-D.
It is essential that the ratio of the master clock frequency to the FSC frequency is exactly
2048. This is of course guaranteed if the FSC signal is generated internally.
5.3.1
When providing the master clock externally, an external clock signal must be connected
to pin MCLK1. The MCLK2 pin must remain unconnected and the CLK_EXT bit in CR0
must be programmed to a logic ’1’. (see the section “CR0 Configuration Register 0
(Filters)” on page 39).
