trigger. Accordingly, data entered through the input port is 15-bit and the least significant bit (bit 0) is fixed
at 0.
Transmission data in this mode is secured at 15-bit word units. The external strobe generator is needed. It
is an effective mode when transmitting A/D converter or counter output. (In the above-mentioned Mode 1
and Mode 2, only bit unit data security can be obtained).
