This chapter gives an overview of the differences between FALC
Version 2.1.
1.1
The value of register VSTR is ´05
Note that decision between V2.1 and V2.2 is possible by reading the MSB´s of the wafer-
ID code (WID register).
1.2
1.2.1
The ID code is
´0100 0000 0000 1011 1110 0000 1000 0011
1.2.2
Pull-up resistors are implemented on pins TCK, TDI, and TMS.
1.3
A pull-up resistor is implemented on this pin.
1.4
MCLK selections between 1.02 MHz and 20.0 MHz work with the appropriate settings of
the registers GCM(1:8).
A selection of valid frequencies and the according clocking register settings are given in
