Writing the ITIFREC register enables or disables

external interrupt on Port C. Each bit can be

masked independantly. The ITMx bit masks the

external interrupt on PC.x.

Bits[7:0] = ITM [7:0] Interrupt Mask

0: external interrupt disabled

1: external interrupt enabled

Writing the ITIFREA register enables or disables

external interrupt on port A.

Bit 7 = Reserved.

Bit 6 = CRDIRM CRD Insertion/Removal Interrupt

Mask

0: CRDIR interrupt disabled

1: CRDIR interrupt enabled

Bits [5:0] = ITM [14:9] Interrupt Mask

Bit x of MISCR2 masks the external interrupt on

port A.x.

Bit x = ITM n Interrupt Mask n

0: external interrupt disabled on PA.x.
