Constructor. JedecID is optional but recommended, since this will ensure that the device is present and has a valid response get this from the datashe

erase a 32Kbyte block

erase a 4Kbyte block

erase a 64Kbyte block

check if the chip is busy erasing/writing

erase entire flash memory array may take several seconds depending on size, but is non blocking so you may wait for this to complete using busy() or c

Send a command to the flash chip, pass TRUE for isWrite when its a write command

cleanup

setup SPI, read device ID etc...

read 1 byte from flash memory

read unlimited # of bytes

Get the manufacturer and device ID bytes (as a short word)

return the STATUS register

Get the 64 bit unique identifier, stores it in UNIQUEID[8]. Only needs to be called once, ie after initialize Returns the byte pointer to the UNIQUEID

Select the flash chip

UNselect the flash chip

Write 1 byte to flash memory WARNING: you can only write to previously erased memory locations (see datasheet) use the block erase commands to first c

write multiple bytes to flash memory (up to 64K) WARNING: you can only write to previously erased memory locations (see datasheet) use the block erase
