Signal descriptions

2.7.4

MIP NDEF Message writing in Progress configuration

(GPO field = 0x3X)

When the GPO is configured as MIP, its state goes to the low state when the RF host writes

the NDEF length to another value than 0x0000.

During an RF session, when M24SR02-Y changes an NDEF file and updates the NDEF

length with a value different from 0x0000, GPO is driven low after a delay (1) following the

beginning of the correspondent UpdateBinary command execution.

GPO will remain low during the writing time (2), before being released.
