Undefined bit, read as 0
Note: *USB definition: when the host sends a set Configuration , the Data pipe should send the DATA0 (about the
Data toggle) first. So, when the Device receives a set configuration setup command, the user needs to toggle
this bit as the following data will send a Data0 first.
**It is only required to set the data pipe as an input pile or output pile. The purpose of this function is to avoid the
host sending a abnormal IN or OUT token and disabling the endpoint.
SETIO (27H) Register, USB Endpoint 1 ~ Endpoint 4 Set IN/OUT Pipe Register
The speaker output volume and speaker mute/un-mute are controlled by the USB Speaker Volume Control register.
The range of the volume is set from 6 dB to -32 dB by software.
Speaker mute control:
MUTEB=0: Mute Speaker output
MUTEB=1: Normal
