High-speed I/O matrix (HSIOM) is a group of high-speed
switches that routes GPIOs to the resources inside the device.
These resources include CapSense, TCPWMs, I2C, SPI, UART,
and LCD. HSIOM_PORT_SELx are 32-bit-wide registers that
control the routing of GPIOs. Each register controls one port; four
dedicated bits are assigned to each GPIO in the port. This
provides up to 16 different options for GPIO routing as shown in
Table 3.
