Registers controlled by I2C USB bus
The registers described in this chapter are controlled through the USB serial I2C interface,
USBSCL and USBSDA balls.
These registers could also be controlled through the main I2C interface, SCL and SDA balls
by setting to “1” USB-I2C_CTRL bit in Power control register (
Table 9.
A bit of register 1 is set at “1” by writing a “1” at address 04h, is reset at “0” by writing a “1” at
address 05h. This is also applicable for USB Control Register 2 (06h, 07h), USB Interrupt
register (0Ah,0Bh), USB Interrupt Mask False register (0Ch, 0Dh) and USB Interrupt Mask
True register (0Eh, 0Fh). Writing “0” at any address has not effect on the content of any
register.
