UART receive error interrupt enable bit

Serial I/O interrupt enable bit

AD conversion complete interrupt enable bit

Key-on wake-up interrupt enable bit

Step 1: Disable all interrupts or the setting interrupts to prevent unnecessary interrupts occurring during setting.

Step 2: Set the each function related the setting interrupts (Note 1).

Note 1: For details, refer to setting method of each function.

In the former, set the Interrupt disable flag (I) to “1”.

In the latter, clear the corresponding interrupt enable bits to “0”.
