Conventions
Register and bit mnemonics are defined in the paragraphs describing them. An overbar is used to designate an active-low signal, eg: RESET. Unless otherwise stated, blank cells in a register diagram indicate that the bit is either unused or reserved; shaded cells indicate that the bit is not described in the following paragraphs; ‘u’ is used to indicate an undefined state (on reset).
