The LPC interface is activated by setting one of the following bits to 1: LPC3E to LPC1E in
HICR0 and LPC4E in HICR4. When the LPC interface is activated, the related I/O ports (P37 to
P30, P83 and P82) function as dedicated LPC interface input/output pins. In addition, setting the
FGA20E, PMEE, LSMIE, and LSCIE bits to 1 adds the related I/O ports (P81, P80, PB0, and
PB1) to the LPC interface's input/output pins.
Use the following procedure to activate the LPC interface after a reset release.
1. Read the signal line status and confirm that the LPC module can be connected. Also check that
2. When using channels 1, 2 and 4, set LADR1, LADR2, and LADR4 to determine the I/O
3. When using channel 3, set LADR3 to determine the I/O address and whether bidirectional data
4. Set the enable bit (LPC4E to LPC1E) for the channel to be used.
5. Set the enable bits (FGA20E, PMEE, LSMIE, and LSCIE) for the additional functions to be
6. Set the selection bits for other functions (SDWNE, IEDIR).
7. As a precaution, clear the interrupt flags (LRST, SDWN, ABRT, OBF, and OBEI). Read IDR
8. Set receive complete interrupt enable bits (IBFIE4 to IBFIE1, ERRIE, and OBEI) as necessary.
