input after the rise of cs. th is input is called a start bit. after input of the start bit, input ope code, address and dat a. address and data are input all in msb first manners. ?0? input after the rise of cs to the start bit input is all ig nored. therefore, when there is li mitation in the bit width of p io of the microcontroller, input ?0?

(dummy bit) is output. and, the following data is output in sync with the rise of sk. this ic has an address auto increment function valid only at read command. this is the function where after the above read execution, by continuously inputting sk clock, the above address data is read sequent ially. and, during the auto increment, keep cs at ?h?. 2) write cycle (write) in this command, input 16bit data (d15 to d0) are written to designated addresses (am to a0). the actual write starts by the fall of cs of d0 taken sk clock. when status is not detected, (cs=?l? fixed) max. 5ms in c onformity with te/w, and when status is detected (cs=?h?), all commands are not accepted for areas where ?l?
