ZHCSA85F August 2012 – February 2019 DLPC410
LOAD4 is enabled by setting the DLPC410 input signal "LOAD4" to a logic '0'. When not using LOAD4, this input should driven or pulled up to logic '1'.
The LOAD4 pin on the DLPC410 was previously defined as "DDC_SPARE_0" pin. DLPC410 referenceschematics may still show this signal as DDC_SPARE_0 even though the DLPR410A enables the LOAD4 capability using this pin. LOAD4 capability is available starting with the DLPR410A and is not available with the DLPR410.
