CR2A(GPIO2 ~ 5& Flash ROM Interface Select
Default 0xFF if PENROM# = 0 during
POR, default 0x00 otherwise)
Bit 7 : (PIN 86 ~89 & 91 ~94)
= 0 GPIO 2
= 1 Flash IF (xD7 ~ XD0)
Bit 6 : (PIN 78 ~ 85)
= 0 GPIO 3
= 1 Flash IF (XA7 ~ XA0)
Bit 5 : (PIN 69 ~ 74 & 76 ~77)
= 0 GPIO 4
= 1 Flash IF (XA!5 ~ XA10 & XA7 ~ A0)
Bit 4: (PIN 66 ~ 68 & 95 ~ 97)

Bit 0~3 : Reserved
7.5 Logical Device 0 (FDC)
CR30 (Default 0x01 if PNPCSV = 0 during POR, default 0x00 otherwise)
Bit 7 - 1: Reserved.
Bit 0: = 1 Activates the logical device.
= 0 Logical device is inactive.
CR60, CR 61 (Default 0x03, 0xf0 if PNPCSV = 0 during POR, default 0x00, 0x00 otherwise)
These two registers select FDC I/O base address [0x100:0xFF8] on 8 byte boundary.
CR70 (Default 0x06 if PNPCSV = 0 during POR, default 0x00 otherwise)
Bit 7 - 4: Reserved.
Bit 3 - 0: These bits select IRQ resource for FDC.
CR74 (Default 0x02 if PNPCSV = 0 during POR, default 0x04 otherwise)
Bit 7 - 3: Reserved.
Bit 2 - 0: These bits select DRQ resource for FDC.
