Conventions
The conventions used in this manual are as follows:

Signals that are preceded by an "n", "/", or “#”character (e.g.: nRD, /RD, or #RD), or
that have a dash on top of the signal name (e.g.: RD) are designated as active low
signals. That is, their active state is when they are driven low, or are driving low.

A "0" indicates a logic zero or low-level signal, while a "1" represents a logic one or
high-level signal.
 The hex-numbers given for addresses of I
2
C devices always represent the 7 MSB of the
address byte. The correct value of the LSB, which depends on the desired command
(read (1), or write (0)), must be added to get the complete address byte. E.g. the given
address in this manual 0x41 => the complete address byte = 0x83 to read from the
device and 0x82 to write to the device.
 Tables which describe jumper settings show the default position in bold, blue text .
