LP5860: About Data Refresh Mode function

Guru 19555 points
Part Number: LP5860

Please let me know about four points below for Data Refresh Mode operation (datasheet page-17).

①8.3.5 is described that Mode1 save the total data volume.

 When Host MCU data transmit, Is Mode1 refresh only dots' data and Mode 2 and 3 refresh all frame data, correct?

 Or, is data volume from Host MCU the same regardless of Mode 1~3? (= data saving is only SRAM's data transmit)

②8.3.5 is described only dots' data update.

 Is data refresh mode object for all of register? (Not only Dot_onoff register)

③Is data update synchronous or non-synchronous by scan line switch?

 When non-synchronous, is there possibility to unintentional lighting by timing of Mode 2~3 and scan line?

④About timing of Mode 1 data update; When Host MCU continue to transmit for auto increment, which is update timing on all data received or the order of received?

 For example, I hope that LP5860EVM lighting the same timing for below RGB LED.
