(in comparison, a [[Teensy 2.0++]] only has 51 lines, not all are useable as programmable I/O) | (in comparison, a [[Teensy 2.0++]] only has 51 lines, not all are useable as programmable I/O) | ||
The lower interface of NAND is exposed complete and also lesser wires/pins than the EBUS. | Because the exposed EBUS is only partial, entire flash will never be accessable, not even when the protocol is 100% reversed.

For this reason, reading/writing to flash is adviced using the <abbr title="Common Flash Interface">CFI</abbr> of the standardised dual [[Flash (Hardware)|NANDs]] (perfectly useable with a [[Teensy 2.0++]]). | For this reason, reading/writing to flash is adviced using the <abbr title="Common Flash Interface">CFI</abbr> of the standardised dual [[Flash (Hardware)|NANDs]] (perfectly useable with a [[Teensy 2.0++]]). | ||
