The 8/16-bit composite timer status control register 0 (Tn0CR0/Tn1CR0) selects

[bit7] IFE: IF flag interrupt enable bit
This bit enables or disables IF flag interrupts.
During timer operation (Tn0CR1/Tn1CR1:STA = 1), the write access to this bit has no effect on operation.
Ensure that the timer has stopped before modifying this bit.
With this bit set to "1", an IF flag interrupt request is output when both the IE bit (Tn0CR1/Tn1CR1:IE) and
the IF flag (Tn0CR1/Tn1CR1:IF) are set to "1".
