/TIOCA3/TMRI0
The pin function is switched as shown below according to the combination of the TPU channel
3 settings (by bits MD3 to MD0 in TMDR_3, bits IOA3 to IOA0 in TIORH_3, and bits
CCLR2 to CCLR0 in TCR_3), bit NDER0*

Notes: *1 Not supported by the H8S/2366.
*2 TIOCA3 input when MD3 to MD0 = B'0000 and IOA3 to IOA0 = B'10xx.
*3 When used as the TMR counter reset pin, set both the CCLR1 and CCLR0 bits in
TCR_1 to 1.
