NOTES :
1. If tw o-phase pulse signal processing is desired, follow ing register settings are required:
• Set the TA2P bit in the UDF register to “1” (tw o-phase pulse signal processing function enabled).
• Set the TA2TGH and TA2TGL bits in the TRGSR register to “00b” (TA2IN pin input).
• Set the port direction bits for TA2IN and TA2OUT to “0” (input mode).
