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 TP
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 are always read as 1.
