W / R = 1/0 Both execute “reload”. *2. It is register access mode when W / R = 0, E 2PROM access mode when W / R = 1. *3. By Switching access to register/E 2PROM, users can select either register or E2PROM when Read/Write. Refer to “ Register and E 2PROM”. Register and E2PROM This IC has an E 2PROM. Data in the E2PROM is maintained despite power-off. The S-7760A has a register which corresponds to the data in the E 2PROM, the S-7760A sends data to this corresponding register during power-on (releasing detection of the low voltage) and inputting the reload command. In case of selecting the RESX pin by option, the S-7760A reloads after releasing reset. The following registers are the ones to be reloaded; ・ Control port register (1-byte) ・ Timer scale setting register (1-byte) ・ DO3 to 0 Timer setting register (1-byte in each port, total 4 bytes) Users are able to switch access between corresponding register and E 2PROM by “Switching access to register/E2PROM” command. Immediately after power-on, the S-7760A is in “register access mode”. In this register access mode, only the register is rewritten, the E 2PROM maintains the prior data. But in “E2PROM access mode”, both data in the register and the E 2PROM is rewritten. In data Read, access mode data which is being selected by user; is read. |
