Unable to read the SRAM of NT3H2111 in pass-through mode

[last_time]

Hi,  everybody:

There is a problem in using NT3H2111.

I use the pass-through mode, and the SRAM_PROT bit is set.

I can write and read the SRAM of NT3H2111 using CLEV6630A in pass-through mode.

I can't read the SRAM when using a phone, but I can write it.When the SRAM_PROT bit is clear, I can read it.

Look forward to your reply. thanks!
