6.2
Firmware hub/low-pin count (FWH/LPC) General-Purpose
Input Register
The FWH/LPC General Purpose Input Register holds the state of the General Purpose
Input pins, GPI0-GPI4. When this register is read, the state of these pins is returned. This
register is read-only. Writing to it has no effect.
The signals on the FWH/LPC Interface General Purpose Input pins should remain constant
throughout the whole Bus Read cycle.
6.3
Manufacturer Code Register
Reading the Manufacturer Code Register returns the value 20h, which is the Manufacturer
Code for STMicroelectronics. This register is read-only. Writing to it has no effect.
