11.2.6 Next Data Register B (NDRB)
NDRB is an 8-bit readable/writable register that stores the next output data for TPC output groups
3 and 2 (pins TP₁₅ to TP₈). During TPC output, when an ITU compare match event specified in
TPCR occurs, NDRB contents are transferred to the corresponding bits in PBDR. The address of
NDRB differs depending on whether TPC output groups 2 and 3 have the same output trigger or
different output triggers.
NDRB is initialized to H'00 by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Same Trigger for TPC Output Groups 2 and 3: If TPC output groups 2 and 3 are triggered by
the same compare match event, the NDRB address is H'FFA4. The upper 4 bits belong to group 3
and the lower 4 bits to group 2. Address H'FFA6 consists entirely of reserved bits that cannot be
modified and always read 1.
