2.2.6 32 bit Flash Memory
For evaluation reasons two 256 MBit MirrorBit Flash memories ( S29GL256N10FFI02 from
Spansion, U503 and U504 ) which can be configured for the 32 bit bus of the JADED are
available on the EVB JADED Interface board.
The 32bit mode can be configured by setting the MPX_MODE_1 [1:0] pins b'10'.
See config switch SW901 on JADE Evaluation board.
2.2.7 USB
A USB 2.0 highspeed mode host and device controller LSI with 16bit width standard CPU bus
S1R72V18 ( U601 ) from Seiko Epson Corporation is populated. The S1R72V18 has two host
ports to function as a USB root hub. One of the ports can be used as a USB device port after
setting.
On the EVB JADED Interface board only the host port will be used.
The interrupt output from the USB controller is connected to the JADED interrupt A1 over 0
Ohm resistor R605, A2 over 0 Ohm resistor R606 and A3 over 0 Ohm resistor R607. Remove
the corresponding resistor to disconnect the connection which shall not be used !
