Each bit in this register controls the enable for one external interrupt. If the bit is set to 1, the interrupt is enabled (if it is not otherwise

masked). If the bit is set to 0, its corresponding interrupt is disabled.

Bit 0: (EIE1.0) External Interrupt 8 Enable (EX8)

Bit 1: (EIE1.1) External Interrupt 9 Enable (EX9)

Bit 2: (EIE1.2) External Interrupt 10 Enable (EX10)

Bit 3: (EIE1.3) External Interrupt 11 Enable (EX11)

Bit 4: (EIE1.4) External Interrupt 12 Enable (EX12)

Bit 5: (EIE1.5) External Interrupt 13 Enable (EX13)

Bit 6: (EIE1.6) External Interrupt 14 Enable (EX14)

Bit 7: (EIE1.7) External Interrupt 15 Enable (EX15)

Bits 0 to 4: (PI4.0 to PI4.4) Port Pin Input Bits for P4.0 to P4.4. Each of these read-only bits reflects the logic state present at the

corresponding port pin.

Bits 5 to 7. (PI4.5 to PI4.7) Reserved

Bits 0 to 7: (PI5.0 to PI5.7) Port Pin Input Bits for P5.0 to P5.7. Each of these read-only bits reflects the logic state present at the

corresponding port pin.
