INT5_0F

INT5_0E

INT5_0C

Notes :

Different names are labeled for those bits which have a different read/write operation

at the same bit position in the peripheral registers.

Bit

INT3F

INT3E

INT2F

INT2E

INT1F

INT1E

INT1CLR

INT3 GLOBAL

INT2 GLOBAL

EXTERNAL INT1

Bit 0

INT1E. External Interrupt 1 Enable.

0 = INT1 disabled

1 = INT1 enabled

Bit 1

INT1F. External Interrupt 1 Flag.

0 = INT1 not requested.

1 = INT1 pending

Bit 2

INT2E. Interrupt 2 Enable

Enables and disables INT2_0 (Timer 1) and INT2_1 (Timer 2)

0 = Disables INT2.

1 = Enables INT2.

Bit 3

INT2F Interrupt 2 Flag

Any INT2_0 or INT2_1 interrupt request sets this bit to 1. To clear this bit,

write 1 to INT2_0C or INT2_1C of IOCTL3 register, the corresponding bit

of interrupt requested.

0 = INT2_0 and INT2_1 are not requested.

1 = INT2_0 or INT2_1 is pending

Bit 4

INT3E. Interrupt 3 Enable

Enables and disables INT3_0 (External) and INT3_1 (Timer 3)

0 = Disables INT3.

1 = Enables INT3.

Bit 5

INT3F. Interrupt 3 Flag

Any INT3_0 or INT3_1 interrupt request sets this bit to 1. To clear this bit,

write 1 to INT3_0C or INT3_1C of IOCTL3 register, the corresponding bit
