T7IFR
When T7 interrupt occurs, this bit becomes ‘1’. The flag is cleared only by writing a ‘0’
to the bit. So, the flag should be cleared by software. Writing “1” has no effect.

When T6 interrupt occurs, this bit becomes ‘1’. The flag is cleared only by writing a ‘0’
to the bit. So, the flag should be cleared by software. Writing “1” has no effect.

EIFLAG1[2:0]
When an External Interrupt 8/9/18(EINT8, EINT9, EINT18) is occurred, the flag
becomes ‘1’. The flag is cleared by writing a ‘0’ to the bit. So, the flag should be
cleared by software. Writing “1” has no effect.
