When I use the bf537, and I set the bf537 boot from SPI . There is an question that confuse me.
When I refer the bf537 datasheet, the datasheet says as follow :
For SPI master mode boot (BMODE = 011), the boot kernel assumes that the
SPI baud rate is SCLK/(2 x 133) Kbit/s. SPI serial EEPROMs that are
8-bit, 16-bit, and 24-bit addressable are supported. The SPI uses the PF10
output pin to select a single SPI EEPROM device. The SPI controller
submits successive read commands at addresses 0x00, 0x0000, and
0x000000 until a valid 8-, 16-, or 24-bit addressable EEPROM is
detected. It then begins clocking data into the beginning of L1 instruction
there is a centence that I marked with red color, say the PF10 is uesd to select the EEPROM device.
So can someone tell me , can I use other pin (for example PF5) to select the EEPROM? And how to do it?
Second. is that each processor use a fixed pin to select the EEPROM when boot from SPI , and can not change?
thank you very much!!
