(ADV7482)EDID

Hi

I have a question about ADV7482 EDID.

ADV7482 hardware manual "ADV748x_HardwareManual_RevPrB_2014-07-11_1.pdf" "5.3.1.4 EDID Controller" has the following description.
--------------------------
The E-EDID/repeater controller is reset when the DVDD supplies go low or when hdcp_rept_edid_reset is set high.When the E-EDID/repeater controller reboots, it performs the following tasks:
? Clears the internal E-EDID and Key Selection Vector (KSV) RAM (refer to Section 5.3.8.2)? Computes a checksum
--------------------------

Does it mean that the checksum is automatically calculated according to the written contents?
The RAM of E-EDID may be cleared, so the operation cannot be imagined.

Best reagrds
