NT3H2111/2211, I2C to NFC address translation for SRAM_MIRROR_BLOCK

prevous thread:
https://community.nxp.com/t5/Wireless-Connectivity/NT3H2111-2211-SRAM-MIRROR-BLOCK-I2C-to-NFC-address-translation/m-p/1201908

I still need clarification on HOW the SRAM_MIRROR_BLOCK address value TRANSLATES

into the NFC side address. The datasheet only indicates the NFC-side address

as 0x04 for the I2C side address value of 0x01. (the page(s) size/block size not-with-standing)

So, when the SRAM_MIRROR_BLOCK address value is 0x01 the NFC side address is 0x04;

but how about when the SRAM_MIRROR_BLOCK address value is set to 0x02?
--> what does the NFC-side address value become? and...

for address value set to 0x03? --> what does the NFC-side address value become? etc.

I guess basically I am asking how far (address value increments) does the

NFC-side beginning SRAM byte move (address-wise) for a SRAM_MIRROR_BLOCK value change?

I hope this helps to understand my question. Perhaps the attached picture will help?

(( I suppose it goes without saying a hole in the memory OR the end of the

memory bound needs to be respected when moving the SRAM location toward

the end of the SECTION. ))

Hello,

You may refer to the table 13 as the datasheet. Example in the table. the value of SRAM_MIRROR_BLOCK is 34h. The value of NFC page is D0H for NTAG I2C pluse 1K. Please refer to the attachment how to transfer it .

Hope it help you. Have a nice day.
