read or write bit. The signals that control an individual FET have an entry
under the FET column. The Component Connected column shows the
board IC that is connected if the FET is enabled. Note that some of the
Microchip (
) output signals are connected directly to components on
U46
the board. However, in most cases, the Microchip (
enable signal of a FET switch. Also note that if a particular functionality
of the processor signal is being used, it will be in bold font under the Pro-
cessor Signal column.
