Note: For key-on wakeup, UART1 bus collision detection, A/D conversion and Timer 1 interrupt,

even if interrupt valid bit (000A16) is set “0: Invalid”,

interrupt discrimination bit (000B16) is set to “1: interrupt occurs”

when corresponding interrupt request occurs.

But corresponding interrupt request bit (003C16, 003D16) is not set to “1”.
