Conversion Length Conversion length (8-bit or 12-bit) is determined by the state of the Ao input, which is latched upon receipt of a conver- sion start transition (described below). IfAo is latched high, the conversion continues for 8 bits. The full 12-bit conver- sion will occur if Ao is low. If all 12 bits are read following an 8-bit conversion, the 3 LSBs (DBO-DB2) will be low (logic 0) and DB3 will be high (logic l). Ao is latched because it is also involved in enabling the output buffers. No other control inputs are latched.
