MVLC_100... is intended for MVLC with large FPGA (standard) MVLC_45... for small FPGA. For very few devices of first series MVLC_45 no longer supported, not enough resources for new features MVLC_100/45_FW0012 trigger_io updates (daq_start) FW0015 event stamper with output buffer implemented. 6010 irq_level0[2:0] // For threshold 0; 1 to 7; 0 = off 6012 irq_level1[2:0] // For Threshold 1; Internal IRQ, 603A start_events // accumulate time stamps 601E irq_event_threshold0[15:0] // max 4k events 6018 irq_event_threshold1[15:0] // max 4k events 6016 max_transfer_data[15:0] // number of time stamps transfered in one BLT access FW0017 DSO built in fixed strobed LUT bugs: 8x universal utils: when used as IRQ inputs FW0018 DSO built in, scans NIM inputs, 6x IRQ inputs Collision bug Counter read and Counter0-FIFO read fixed. FW0020 VME bus timeout increased from 1.6us to 16us Multi crate synchronisation implemented in Hardware Some new stack commands implemented (still undocumented) FW0021 Multicrate features implemented, CR/CSR space addressing for some modules (am codes extended). Timing optimisations FW0022 Multicrate synchronisation improved; Error capture at VME read/write -> blink signal at front LEDs FW0023 extend signal to IRQ translation table to 8 entries (0x7000 to 0x701E) FW0024 new Reg 0x7020 : assign unassigned signals to specified internal IRQ Fix Trig IO glitches (from FW0022) FW0026 minor fixes, max Stack size increased from 1kWords to 2kWords. read/write with Berr response -> fixed error message.
