General Purpose I/O Header
The JGP1 (General Purpose Input/Output) header is a general purpose I/O expander on a
pin header via the SMBus. Each pin can be configured to be an input pin or output pin. The
GPIO is controlled via the PCA9554APW 8-bit GPIO expansion from PCH SMBus. The base
address is 0xF040. The expander slave address is 0x4C for WRITE and READ. See the table
below for pin definitions.
