EI2C - Enable external interrupt 3. EI2C = 0 disables
Reserved. Read as 1.
EX6 - Enable external interrupt 6. EX6 = 0 disables external
interrupt 6 (INT6). EX6 = 1 enables interrupts generated by
the INT6 pin.
EX5 - Enable external interrupt 5. EX5 = 0 disables external
interrupt 5 (INT5). EX5 = 1 enables interrupts generated by
the INT5# pin.
EX4 - Enable external interrupt 4. EX4 = 0 disables external
interrupt 4 (INT4). EX4 = 1 enables interrupts generated by
the INT4 pin.
external interrupt 3 (INT3). EI2C = 1 enables interrupts
generated by the I
EUSB - Enable USB interrupt. EUSB = 0 disables USB
interrupts. EUSB = 1 enables interrupts generated by the
USB Interface.
