Table 2-8 and Table 2-9 show the output signals of the Microchip GPIO
expander (
U38
), with a TWI address of 0100 010X, where X represents the
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 (
U38
) output signals are connected directly to components on
the board. However, in most cases, the Microchip (
U38
) is controlling the
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.
