11 / 44 page PROGRAMMABLE PORT CONTROLLER (PORT EXPANDER WITH BUILT-IN E2PROM CIRCUIT) Rev.1.1_00 S-7750C Seiko Instruments Inc. 11 Configuration of Command If setting C TA / , the bit for timer address setting / command switch, in “0”, address / command (C2, C1, C0) is recognized as command. There are 8 types of command, and Read / Write in each register is done by them. If setting the bit for timer address setting / command switch ) C (TA / in “1”, the S-7750C recognizes this command as timer setting for DO0 to DO7.

By inputting dummy data, the master device sends data in 18-bit during transmission. However, the S-7750C executes the command when it has loaded 9-bit. Regarding acknowledgment, refer to “ Operation 4. Acknowledgment”. *2. W / R = “0”; register access mode, W / R = “1”; E 2PROM access mode *3. To switch access to register / E 2PROM, use the “Switching access to register / E2PROM” command. When rewriting the E 2PROM, the register is rewritten simultaneously. Register and E2PROM In the S-7750C, the register and the E 2PROM correspond each other. The S-7750C maintains the default value for control despite power-off due to the included E 2PROM. The data in the register is installed in the E2PROM by using the reload command. And the data in the E 2PROM is automatically installed into the register when power-on and the lower power supply voltage is applied. Restoring the default value for control is possible any time due to these functions. These 12 commands have the configuration in which the register and E 2PROM correspond. ・ Free area 1, 2 ・ Control port ・ Setting for timer scale ・ Timer setting for DO7 to DO0 Users are able to switch access between corresponding register and E 2PROM by the “Switching access to register / E 2PROM” command. Immediately after power-on, the S-7750C is in the “register access mode”. In this register access mode, only the register is rewritten, the E 2PROM maintains the prior data. But in the “E2PROM access mode”, data both in the register and the E 2PROM is rewritten. In data Read, access mode data which is being selected by user; is read. |
