Section 10 Multi-Function Timer Pulse Unit 2 (MTU2)
10.3.29 Timer Interrupt Skipping Counter (TITCNT)
TITCNT is an 8-bit readable/writable counter. The MTU2 has one TITCNT. TITCNT retains its
value even after stopping the count operation of TCNT_3 and TCNT_4.

TGIA_3 Interrupt Counter
While the T3AEN bit in TITCR is set to 1, the count in
these bits is incremented every time a TGIA_3 interrupt
occurs.
[Clearing conditions]
• When the 3ACNT2 to 3ACNT0 value in TITCNT
matches the 3ACOR2 to 3ACOR0 value in TITCR
• When the T3AEN bit in TITCR is cleared to 0
• When the 3ACOR2 to 3ACOR0 bits in TITCR are
cleared to 0

TCIV_4 Interrupt Counter
While the T4VEN bit in TITCR is set to 1, the count in
these bits is incremented every time a TCIV_4 interrupt
occurs.
[Clearing conditions]
• When the 4VCNT2 to 4VCNT0 value in TITCNT
matches the 4VCOR2 to 4VCOR2 value in TITCR
• When the T4VEN bit in TITCR is cleared to 0
• When the 4VCOR2 to 4VCOR2 bits in TITCR are
cleared to 0
Note: To clear the TITCNT, clear the bits T3AEN and T4VEN in TITCR to 0.
