Table 5. Parameters
Parameter Name Field Usage Field Format
devicecode Device code as defined in “devices.h” 1 byte
revision Device revision. Currently not used. Should be set to 0. 1 byte
progtype Defines which Program modes is supported:
“0” – Both Parallel/High-voltage and Serial mode
“1” – Only Parallel/High-voltage mode
1 byte
parmode Defines if the device has a full parallel interface or a
pseudo parallel programming interface:
“0” – Pseudo parallel interface
“1” – Full parallel interface
1 byte
polling Defines if polling may be used during SPI access:
“0” – No polling may be used
“1” – Polling may be used
1 byte
selftimed Defines if programming instructions are self timed:
“0” – Not self timed
“1” – Self timed
1 byte
lockbytes Number of Lock bytes. Currently not used. Should be set
to actual number of Lock bytes for future compability.
1 byte
fusebytes Number of Fuse bytes. Currently not used. Should be set
to actual number of Fuse bytes for future caompability.
