31 OLD:
32 1kB each header
33 with predive header at beginning
34 and postdive header with 0x400 HEADER2OFFSET
35 4kB (one erase) has two dives with 4 headers total
36 total of 512 kB (with 256 header ids (8 bit))
37 Size is 280 Byte (as of 25.Nov. 2014)
38
39 [..] Output to PC / UART is postdive header
40
41 [..] Block Protection Lock-Down is to erase logbook only
42
43 [..] Timing (see page 137 of LOGBOOK_V3_S25FS-S_00-271247.pdf
44 bulk erase is 2 minutes typ., 6 minutes max.
