Notes: 1. TIOCC3-B input when MD3 to MD0 = B'0000 and IOC3 to IOC0 = B'10xx.
2. IRQ1-A input when the ITS1 bit in ITSR is 0.
3. When used as the external clock input pin for the TMR, its pin function should be
specified to the external clock input by the CKS2 to CKS0 bits in TCR_0 after the TMRS
bit in PFCR3 is set to 1.
4. TIOCD3-B output disabled. Output disabled and settings (2) effective when BFA = 1 or
BFB = 1 in TMDR_3.
5. NMOS open-drain output regardless of P51ODR.
6. When using as PO2-B output, set PPGS in PFCR3 to 1 before other register setting.
7. When using as TIOCC3-B input/output, set TPUS in PFCR3 to 1 before other register
setting.
8. When using as TMCI0-B input, set TMRS in PFCR3 to 1 before other register setting.
