3.2.4.4 Interrupt Status Register, Address [0Dh]
This Read/Write register serves as an Interrupt status register when it is read, and an Interrupt clear register when it is written.
To clear an interrupt, the register must be written with the appropriate bit set to 1. Writing a 0 has no effect on the status.
Table 3-32. Interrupt Status Register [Address 0Dh]
3.2.4.5 Current Data Set Register, Address [0Eh]
This register indicates currently selected data set for each endpoint.
Table 3-33. Current Data Set Register [Address 0Eh]
3.2.4.6 Control Register 2, Address [0Fh]
Control Register 2 is used to control if the device is configured as a master or a slave and can change the polarity of the Data+
and Data- pins to accommodate both full and low speed operation.
