Epson S1C17624 Technical Manual page 130

If T16IE is set to 0 (interrupt disabled, default), no interrupt request will be sent to the ITC.
For specific information on interrupt processing, see the "Interrupt Controller (ITC)" chapter.
notes: • The T16 module interrupt flag T16IF must be reset in the interrupt handler routine after a T16
interrupt has occurred to prevent recurring interrupts.
• Reset T16IF before enabling T16 interrupts with T16IE to prevent occurrence of unwanted in-
terrupt. T16IF is reset by writing 1.
