T8OIF is the T8OSC1 module interrupt flag. Setting T8OIE (D0/T8OSC1_IMSK register) to 1 sets this
to 1 when the counter matches the compare data register setting during counting. An 8-bit OSC1 timer
interrupt request signal output simultaneously to the ITC sets the ITC 8-bit OSC1 timer interrupt flag to
1 and generates an interrupt if the ITC and S1C17 core interrupt conditions are met.
The following processes must be performed to manage the interrupt factor occurrence state using this
register.
1. Set the ITC 8-bit OSC1 timer interrupt trigger mode to level trigger mode.
2. Reset the T8OSC1 module interrupt flag T8OIF within the interrupt processing routine after the in-
terrupt occurs (this also resets the ITC interrupt flag).
T8OIF is reset by writing as 1.
Note: To prevent generating unnecessary interrupts, reset T8OIF before permitting compare
match interrupts using T8OIE (D0/T8OSC1_IMSK register).
