Table 8-1 Control Registers
1. "byte, bit" means that register can be addressed by not only bit
but byte manipulation instruction.
2. "byte" means that register can be addressed by only byte
manipulation instruction. On the other hand, do not use any
read-modify-write instruction such as bit manipulation for
clearing bit.
3. RA is one-bit high-voltage input only port pin. In addition, RA
serves the functions of the Vdisp special features. Vdisp is
used as a high-voltage input power supply pin when selected
by the mask option.
