11.2.5 Next Data Register A (NDRA)
NDRA is an 8-bit readable/writable register that stores the next output data for TPC output groups
1 and 0 (pins TP₇ to TP₀). During TPC output, when an ITU compare match event specified in
TPCR occurs, NDRA contents are transferred to the corresponding bits in PADR. The address of
NDRA differs depending on whether TPC output groups 0 and 1 have the same output trigger or
different output triggers.
NDRA 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 0 and 1: If TPC output groups 0 and 1 are triggered by
the same compare match event, the NDRA address is H'FFA5. The upper 4 bits belong to group 1
and the lower 4 bits to group 0. Address H'FFA7 consists entirely of reserved bits that cannot be
modified and are always read as 1.
