Table 5.7: NAND Flash Connection
To enable boot for the NAND FLASH, set SW6 pins 1/2/3 to OFF. The NAND device is 256MByte in size,
however, it should be noted however, that only 64MByte is addressable. Refer to section 6.1.5 for further
details.
5.10
Dual QSPI Flash
The RSK+ board provides two 64MByte Serial Flash memory ICs, IC25 and IC26, which connect to the
RZ/A1H MCU via the SPI Multi I/O Bus Controller. Signal Connections are detailed in Table 5.8 below.
