1. We search below description in datasheet, that the bootstrip pin isn't programmable via MUXMODE after the bootstrip is set to BOOTMODE, but we consider it is very waste because there are about 16pin bootstrip;
and we want to know that if we can set the bootstrip pin to other function for the MAXMODE( like the GPMC/ GPIO and so on);
2. We use the GPMC for the extend 16Bit SRAM for the FPGA communication, and now we want to konw how to identify the high and low 8 bits;

Hello Zhang Liang
Thank you for the query
The Boot mode pins have alternative functionality as below.
Please refer the EVM where the bootmode pins have alternate functions setup.
We use the GPMC for the extend 16Bit SRAM for the FPGA communication, and now we want to konw how to identify the high and low 8 bits;
Could you please provide additional inputs. A block diagram would help.
For the 16-bit interface, i am trying to understand the need for indication the lower and higher 8-bits ?

Hi Kallikuppa,
This is a very used for our current design for the bootmode pins;
and please refer to below our schematic diagram for the GPMC and SARM:
