Read/Write Register Command

The write register command is most sensitive to the duty cycle. Whereas the read register works in a wide range, except for a one 

Write Register Command

The command sequence was:
reset chip -> write register -> read register


Read Register command

The command sequence was:
reset chip -> read register
The analog sections was power so that also the channel and calibration mask was readout.
The following figures shows two different ranges for the read register command:
The two curves min-curve and glitch-occurs-curve enclosure the range where the reading of the register and the two masks is working. If the duty cycle is between the two curves glitch-occurs and max the reading of the register is still working fine but the first bit from the masks is always zero. The following 255 mask bits are ok.
