USB DEVICE CONTROLLER SPECIAL REGISTERS
This section describes detailed functionalities about register sets of USB device controller.
All special function register is byte-accessible or word-accessible. If you access byte mode offset-address is
different in little endian and big endian. All reserved bit is zero.
Common indexed registers depend on INDEX register (INDEX_REG) (offset address: 0X178) value. For example
if you want to write EP0 CSR register, you must write ‘0x00’ on the INDEX_REG before writing IN_CSR1 register.
NOTE
All register must be resettled after performing Host Reset Signaling.
