Section 19 Host Interface LPC Interface (LPC)
Unlike the IDR and ODR registers, the transfer direction is not fixed for the bidirectional data
registers (TWR). MWMF and SWMF are provided in STR to handle this situation. After writing
to TWR0, MWMF and SWMF must be used to confirm that the write authority for TWR1 to
TWR15 has been obtained.
Table 19.9 shows host address examples for LADR3 and registers, IDR3, ODR3, STR3,
TWR0MW, TWR0SW, and TWR1 to TWR15 when LADR3 = H'A24F and LADR3 = H'3FD0.
