202 / 712 page  7. I/O Ports Rev.2.00 Mar. 22, 2007 Page 178 of 684 REJ09B0352-0200 PBDR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it retains its previous setting. When port B pins are used for TPC output, PBDR stores output data for TPC output groups 2 and 3. If a bit in the next data enable register (NDERB) is set to 1, the corresponding PBDR bit cannot be written. In this case, PBDR can be updated only when data is transferred from NDRB. 7.11.3 Pin Functions The port B pins are also used for TPC output (TP 15, TP13 to TP8), ITU input/output (TIOCB4, TIOCB 3, TIOCA4, TIOCA3) and output (TOCXB4, TOCXA4), and ADTRG input. Table 7.18 describes the selection of pin functions. |
