Bit 3 of register TSTP controls the datapath reset signal. A value of ‘0’ holds the datapath in a reset condition,
while a value of ‘1’, places the datapath in normal mode. The datapath is also reset at power on by an internally
generated power on reset signal.
CH7301A
Bit 4 of register TSTP controls the IIC reset signal. A value of ‘0’ holds the IIC registers in a reset condition, while
a value of ‘1’, places the IIC registers in normal mode. The IIC registers are also reset at power on by an internally
generated power on reset signal.

Register VID is a read only register containing the version ID number of the CH7301. The MV default is ‘1’ when
the CH7301 is bonded out with Macrovision enabled, and ‘0’ when the CH7301 is bonded out with Macrovision
disabled.
