Command
(29) Cancel EEPROM Control (EPCOUT) Command: 1 Parameter: 0
This command cancels the EEPROM (S1F17A10) Control mode. If data is read from the EEPROM, both of Electronic
Control value and built-in resistance ratio are updated by the read data.
(30) Write Into EEPROM (EPMWR) Command: 1 Parameter: 0
This command writes the Electronic Control value and built-in resistance ratio into the EEPROM (S1F17A10).
(31) Read From EEPROM (EPMRD) Command: 1 Parameter: 0
This command reads the Electronic Control value and built-in resistance ratio from the EEPROM (S1F17A10), and
temporarily stores them in S1D15G10 registers.
(32) Read Register 1 (EPSRRD1) Command: 1 Parameter: 0
Issue the EPSRRD1 and STREAD (Status Read) commands in succession to read the Electronic Control value.
Issue the Status Read command immediately after this command. Also, always issue the NOP command after the
STREAD (Status Read) command.
