Cautions
1) t_GTP and t_GTA in the tables are typical values. A variation of ±1ms should be considered.
2) If guard time GTPn (n = 0 to 3) is set to 0000, a wrong decoding result may be output. Therefore,
avoid such setting.
3) If guard time GTAn (n = 0 to 3) is set to 0000 and 0001, the interdigit pause reject time cannot be
acquired. Therefore, avoid such settings.
