Note: The new value of PNPCVS must be complementary to the old one to make an effective change. For example, the user must
set PNPCVS to 1 first and then reset it to 0 to reset these PnP registers if the present value of PNPCVS is 0.

HEFRAS (bit 0): combines with HEFERE (CR0C bit 5) to define how to access Extended Function
Registers (refer to CR0C bit 5 description). The corresponding power-on setting pin
is nDTRA (pin 35).
8.2.23 Configuration Register 17 (CR17), default = 00H
When the device is in Extended Function mode and EFIR is 17H, the CR17 register can be accessed
through EFDR. The bit definitions are as follows:
