When writing is made into the TMJ under the timer mode, the counters (TCJ and TCK) will be
initialized (H'FF). Consequently, writing into the reloading registers (TLJ an TLK) should be
conducted after finishing settings with the TMJ.
Under the remote controlling mode, although the TLJ and the TLK will not be initialized even
when writing is made into the TMJ, follow the sequence listed below when starting a remote
controlling operation.
(1) Make setting to the remote controlling mode with the TMJ.
(2) Write the data into the TLJ and TLK.
(3) Start the remote controlled operation by use of the TMJ. (ST bit = 1)
Even under 16-bit operations, TMJ1I interrupt requests from the TMJ-1 will be valid.
