INDEX REGISTER (INDEX_REG)
The INDEX register is used to indicate certain endpoint registers effectively. The MCU can access the endpoint
registers (MAXP_REG, IN_CSR1_REG, IN_CSR2_REG, OUT_CSR1_REG, OUT_CSR2_REG,
OUT_FIFO_CNT1_REG, and OUT_FIFO_CNT2_REG) for an endpoint inside the core using the INDEX register.
