EX0
P3.2
Enables or disables EXTERNAL0 interrupt. If EX0 = 0, the external interrupt 0 is
disabled.
Enables or disables the TIMER 0 overflow interrupt. If ET0 = 0, the Timer 0 interrupt
is disabled.
Enables or disables the EXTERNAL1 interrupt. If EX1 = 0, external interrupt 1 is
disabled.
Enables or disables TIMER 1 overflow interrupt. If ET1 = 0, the Timer 1 interrupt is
disabled.
Enables or disables the UART interrupt. If ES0 = 0, the UART interrupt is disabled.
Enables or disables the I
2
C-bus interrupt. If ES1 = 0, the I
2
C-bus interrupt is disabled.
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.

Enables or disables interrupts on P1.0. If EX2 = 0, the corresponding interrupt is
disabled.
Enables or disables interrupts on P1.1. If EX3 = 0, the corresponding interrupt is
disabled.
Enables or disables interrupts on P1.2. If EX4 = 0, the corresponding interrupt is
disabled.
Enables or disables the SYMBOL interrupt. If EX5 = 0, the SYMBOL interrupt is
disabled.
Enables or disables interrupts on P1.4. If EX6 = 0, the corresponding interrupt is
disabled.
Enables or disables the DC/DC CONVERTER interrupt. If EX7 = 0, the DC/DC
converter interrupt is disabled.
Enables or disables interrupts on the WATCHDOG. If EX8 = 0, the WDINT interrupt is
disabled.
Enables or disables REAL-TIME CLOCK interrupt. If EX9 = 0, the MINUTE interrupt
is disabled.
