Timer Interrupt Skipping Counter (TITCNT)

TITCNT is an 8-bit readable/writable counter. The MTU2 has one TITCNT. TITCNT retains the

value even after TCNT_3 or TCNT_4 stops counting.

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:

Clear the T3AEN and T4VEN bits in TITCR to 0, to clear the value of TITCNT.
