SYSTEM CONTROL REGISTER 2 (0x05)
Bit D6 is a control bit and bit D5 is a configuration bit.
When bit D6 is set low, the system starts playing; otherwise, the outputs are shut down.
Bit D5 defines the configuration of the system, that is, it determines what configuration the system runs in when
bit D6 is set low. When this bit is asserted, all channels are switching. Otherwise, only a subset of the PWM
channels will run. The channels to shut down are defined in the shutdown group register (0x19). Bit D5 should
only be changed when bit D6 is set, meaning that it is only possible to switch configurations by resetting the DAP
and then restarting it again in the new configuration.
