Different Triggers for TPC Output Groups 2 and 3: If TPC output groups 2 and 3 are triggered
by different compare match events, the address of the upper 4 bits of NDRB (group 3) is H'FFFA4
and the address of the lower 4 bits (group 2) is H'FFFA6. Bits 3 to 0 of address H'FFFA4 and bits
7 to 4 of address H'FFFA6 are reserved bits that cannot be modified and always read 1.
