This parameter is intended to be used as a way of telling if the power on STK600 has
been lost or turned off and then back again.
This way, the host software can tell if the programmer needs to be initialized again
before continuing with its operation.
If the returned value is 0 the CMD_SET_CONTROL_STACK must be executed
before continuing with any high voltage programming commands.
This parameter sets a time period for which the reset line has a higher resistance for
each time it is toggled.
The purpose is to reduce the maximum current caused by the discharge/recharge of
a decoupling capacitor connected to the reset pin.
When the reset is toggled a resistor of 510ohm will be switched in, which reduces the
peak current to an acceptable level for the internal components of the STK600.
The delay should be set to: t>510ohm*C
If no capacitor is connected this parameter could be set to 0.
The parameter value is voltage in volts x100, i.e. a parameter value of 449 (decimal)
corresponds to 4.49V.
The maximum value is 5.5V, or parameter value 550.
Same as for AREF0.
This is a two-byte value, which configures the chip oscillator.
The frequency is given by the formula:
