-====== Avalable Functions ======
-The functions given below have so far been implemented as VHDL modules (see [[software:flink:flink_vhdl|VHDL]]). For all of them a suitable driver is available in the [[software:flink:flink_lib|flink Userspace Library]]
-^function id^name^description^
-|0x00|unused|this function id is not used|
-|0x01|AnalogIn|analog input, ADC|
-|0x02|AnalogOut|analog output, DAC|
-|0x0c|PWM|pulse width modulated outputs|
-==== Subdevice Specific Registers ====
-As described in [[software:flink|flink, Universal Serial Interface to FPGA's]] every subdevice realizes a certain function. The function id together with status and configuration registers can be found in the header and subheader section. Every subdevice has further registers which are specific for a certain function. These registers are described below for the available functions.

-^Offset^Size [byte] ^Name^r/w^Const^Description^
-|0x20|4|base_clk|r|no|base clock in Hz|
-|0x24|4|ptime_0|r/w|no|channel 0: period in multiples of base clock|
-|0x28|4|ptime_1|r/w|no|channel 1: period in multiples of base clock|

-|0xyy|4|htime_0|r/w|no|channel 0: high time in multiples of base clock|
-|0xyy+4|4|htime_1|r/w|no|channel 1: high time in multiples of base clock|
-|..|4|..|r/w|no|..|
