Notes: 1. IRQ3-B input when the ITS3 bit in ITSR is 1.
2. TIOCD3-B input when MD3 to MD0 = B'0000 and IOD3 to IOD0 = B'10xx.
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_1 after the TMRS
bit in PFCR3 is set to 1.
4. When using as PO3-B output, set PPGS in PFCR3 to 1 before other register setting.
5. When using as TIOCD3-B input/output, set TPUS in PFCR3 to 1 before other register
setting.
6. When using as TMCI1-B input, set TMRS in PFCR3 to 1 before other register setting.
