Capable of both read and write access
Read only
Read only. After reading the register bank, each bit which is HIGH(1) will be cleared to LOW(0 )
automatically.
Write only
Write only. When writing data bits to register bank, each bit which is HIGH(1) will cause the
corresponding bit to be set to 1. Data bits which are LOW(0) has no effect on the corresponding bit.
