Enable Bit = 1 enables the interrupt .

Enable Bit = 0 disables it .

EA (IE.7): 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.

EPCA_LVD (IE.6): Interrupt controller of Programmable Counter Array (PCA) and Low-Voltage Detector.

0 : Disable the interrupt of Programmable Counter Array (PCA) and Low-Voltage Detector

1 : Enable the interrupt of Programmable Counter Array (PCA) and Low-Voltage Detector

EADC_SPI (IE.5): Interrupt controller of Serial Peripheral Interface (SPI) and A/D Converter (ADC).

0 : Disable the interrupt of Serial Peripheral Interface (SPI) and A/D Converter (ADC).

1 : Enable the interrupt of Serial Peripheral Interface (SPI) and A/D Converter (ADC).

ES (IE.4): Serial Port 1 (UART1) interrupt enable bit. If ES = 0, UART1 interrupt will be diabled. If ES = 1, UART1

interrupt is enabled.

ET1 (IE.3): Timer 1 interrupt enable bit. If ET1 = 0, Timer 1 interrupt will be diabled. If ET1 = 1, Timer 1 interrupt is

enabled.

EX1 (IE.2): External interrupt 1 enable bit. If EX1 = 0, external interrupt 1 will be diabled. If EX1 = 1, external

interrupt 1 is enabled.

ET0 (IE.1): Timer 0 interrupt enable bit. If ET0 = 0, Timer 0 interrupt will be diabled. If ET0 = 1, Timer 0 interrupt is

enabled.

EX0 (IE.0): External interrupt 0 enable bit. If EX0 = 0, external interrupt 0 will be diabled. If EX0 = 1, external

interrupt 0 is enabled.

ESPI

ELVDI

ELVDI : Enable/Disable interrupt from low-voltage sensor

0 : (default)Inhibit the low-voltage sensor functional block to generate interrupt to the MCU

1 : Enable the low-voltage sensor functional block to generate interrupt to the MCU

ESPI : Enable/Disable interrupt from Serial Peripheral Interface (SPI)

0 : (default)Inhibit the SPI functional block to generate interrupt to the MCU

1 : Enable the SPI functional block to generate interrupt to the MCU

EADCI : Enable/Disable interrupt from A/D converter

0 : (default) Inhibit the ADC functional block to generate interrupt to the MCU

1 : Enable the ADC functional block to generate interrupt to the MCU

UART_M0x6 : Baud rate select bit of UART1 while it is working under Mode-0

0 : The baud-rate of UART in mode 0 is SYSclk/12.

1 : The baud-rate of UART in mode 0 is SYSclk/2.
