NOTE: The Mark of 'R[W]' in R/W column means that each register can be set in read or write mode, but once it is set to
one mode, it cannot operate in the other mode. For example, USBEP1 is set to 'R' in setup time, it can be read but
not be written. So, if you want to write something in USBEP1 after it is set to R mode, you must re-setup the register
to 'W' mode.
