Reset
The FALC54 is forced to the reset state if a high signal is input at port RES for a minimum
period of 20 s. During RESET, all output stages except CLK16M, CLK12M, CLK8M,
CLKX, FSC, XCLK and RCLK are tri-stated, all internal flip-flops are reset and most of
the control registers are initialized with default values.
After Reset bit FMR1.PMOD has to be set high and the device needs up to 20 sec to
settle up to the internal clocking. After FMR1.PMOD has been set the configuration
shown in table 24 is initialized.
