Part Order Number
A pin is an external physical connection. The same pin can be used to connect a number of signals.
Asserted means that a discrete signal is in active logic state.
— Active low signals change from logic level one to logic level zero.
— Active high signals change from logic level zero to logic level one.
Negated means that an asserted discrete signal changes logic state.
— Active low signals change from logic level zero to logic level one.
— Active high signals change from logic level one to logic level zero.
LSB means least significant bit or bits, and MSB means most significant bit or bits. References to low and
high bytes or words are spelled out.
Numbers preceded by a percent sign (%) are binary. Numbers preceded by a dollar sign ($) or 0x are
hexadecimal.
