General purpose I/O port 3 bit 4.
Secondary LRESET# output 4.
General purpose I/O port 3 bit 5
General purpose I/O port 3 bit 6
General purpose I/O port 3 bit 7
General purpose I/O port 5 bit 0.
During VSB power reset (RSMRST), this pin is pulled down
internally and is defined as VID transition voltage level, which
provides the value for CR2C bit 3.
and a 1 kΩ is recommended if intends to pull up.
