NAME

SOURCE

NOTES

IEN0 address A8H: interrupt enable for X0, X1, T0, T1, T2, S0, S1 and global interrupt enable (note 1)

EX0

P3.2

Enables or disables EXTERNAL0 interrupt. If EX0 = 0, the external interrupt 0 is

disabled.

ET0

TIMER 0

Enables or disables the TIMER 0 overﬂow interrupt. If ET0 = 0, the Timer 0 interrupt

is disabled.

EX1

P3.3

Enables or disables the EXTERNAL1 interrupt. If EX1 = 0, external interrupt 1 is

disabled.

ET1

TIMER 1

Enables or disables TIMER 1 overﬂow interrupt. If ET1 = 0, the Timer 1 interrupt is

disabled.

ES0

UART

Enables or disables the UART interrupt. If ES0 = 0, the UART interrupt is disabled.

ES1

I2C

Enables or disables the I2C-bus interrupt. If ES1 = 0, the I2C-bus interrupt is disabled.

ET2

WAKE-UP Enables or disables the WAKE-UP interrupt. If ET2 = 0, the wake-up interrupt is

disabled.

Disables all interrupts. If EA = 0, no interrupt will be acknowledged. If EA = 1, each

interrupt source is individually enabled or disabled by setting or clearing its enable bit.

IEN1 address E8H: interrupt enable for X2 to X9 (note 1)

EX2

P1.0

Enables or disables interrupts on P1.0. If EX2 = 0, the corresponding interrupt is

disabled.

EX3

P1.1

Enables or disables interrupts on P1.1. If EX3 = 0, the corresponding interrupt is

disabled.

EX4

P1.2

Enables or disables interrupts on P1.2. If EX4 = 0, the corresponding interrupt is

disabled.

EX5

SYMBOL

Enables or disables the SYMBOL interrupt. If EX5 = 0, the SYMBOL interrupt is

disabled.

EX6

P1.4

Enables or disables interrupts on P1.4. If EX6 = 0, the corresponding interrupt is

disabled.

EX7

DC/DC

Enables or disables the DC/DC CONVERTER interrupt. If EX7 = 0, the DC/DC

converter interrupt is disabled.

EX8

WDI

Enables or disables interrupts on the WATCHDOG. If EX8 = 0, the WDINT interrupt is

disabled.

EX9

MIN

Enables or disables REAL-TIME CLOCK interrupt. If EX9 = 0, the MINUTE interrupt

is disabled.

IP0 address B8H: interrupt priority for X0, X1, T0, T1, T2, S0 and S1 (note 2)

PX0

P3.2

Deﬁnes the EXTERNAL0 interrupt 0 priority level. PX0 = 1 programs it to the higher

priority level.

PT0

TIMER 0

Enables or disables the TIMER 0 interrupt priority level. PT0 = 1 programs it to the

higher priority level.

PX1

P3.3

Deﬁnes the EXTERNAL1 interrupt priority level. PX1 = 1 programs it to the higher

priority level.

PT1

TIMER 1

Deﬁnes the TIMER 1 interrupt priority level. PT1 = 1 programs it to the higher priority

level.
