| 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. | |

| 52 ##### bug fixes ##### | |
| 53 ============================================================================== | |
| 54 150917: end in header and length of sample was one byte too long | |
