NAND Flash
The SAM4E Xplained Pro kit has one external Micron MT29F2G08ABAEAWP:E 2Gb NAND flash connected
to the external bus interface of the SAM4E. The NAND flash is connected to chip select NCS0. NAND flash
access can be configures in the Static Memory Controller in the SAM4E.
The R/B (read / busy) signal from the NAND flash is connected to PB12 which is configured as SAM4E
chip erase by default. In order to utulize the R/B signal PB12 must be configured as a normal I/O pin in the
CCFG_SYSIO register located in the MATRIX module and the internal pull-up has to be enabled. For more
information see the SAM4E datasheet.
