During power-on strapping with external pulled-down 10k resistor.
Then it will disable LA [19:17] function and pin108~pin111, pin29
use as GPIO2X function.

DMA Acknowledge channel 6.
During power-on reset, this pin is pulled-up internally(Select
4Eh) ,and is defined as HEFRAS which provides the power-on
value for CR3 bit4 .A 10k ohm is recommended if intends to pull
down .(Select 2Eh)
