E_PWMOMD[2:0]
These EEPROM contain the configuration data of output type for the OUT pin. The output type
configuration of the OUT pin provides Push-pull and NMOS-open-drain. To validate the user
configuration in Normal Mode, store the configuration data to E_PWMOMD via WriteEEPROM operation
code in User Mode.
OUT pin output type E_PWMOMD[2:0]
Default
Push-Pull
0x0
●
NMOS-Open-Drain
0x7
WARNING: If a data except “0x0” and “0x7” is set to E_PWMOMD[2:0] bits, the OUT pin output type can
not be guaranteed.

These EEPROM contain the configuration data for the moving average filter of processing angle data.
The configuration of the moving average filter provides SPC (2 times averaging), HP (8 times averaging)
and OFF (without averaging procedure). To validate the user configuration in Normal Mode, store the
configuration data to E_IT via WriteEEPROM operation code in User Mode.

OFF
0x3F
WARNING: If a data except “0x0”, “0x7” and “0x3F” is set to E_IT[5:0] bits, the moving average filter can
not be guaranteed.
