32.4 Product Dependencies
32.4.1 GPIO
SCLK, DATA[3..0], BS & INS are I/O lines, multiplexed with other I/O lines. The I/O controller
must be configured so that MSI can drive these I/O lines.
32.4.2 Power Manager
MSI is clocked through the Power Manager (PM), thus programmer must first configure the PM
to enable the CLK_MSI clock.
