15.6
15.6.1
LPC operation can be enabled or disabled using the module stop control register. The initial
setting is for LPC operation to be halted. Register access is enabled by canceling module stop
mode. For details, refer to section 19, Power-Down Modes.
15.6.2
The host interface provides buffering of asynchronous data from the host processor and slave
processor (this LSI), but an interface protocol that uses the flags in STR must be followed to avoid
data contention. For example, if the host and slave processor both try to access IDR or ODR at the
same time, the data will be corrupted. To prevent simultaneous accesses, IBF and OBF must be
used to allow access only to data for which writing has finished.
