Generic VME module registers

It is required to comply with this specification for module to be automatically configured in VMEDAQ.

Module shall support:

• CR/CSR (AM 0x37, custom spec, not VME64)
• A16 D32 R/W (AM 0x29) - register I/O
• A24 D32 R/W (AM 0x39) - memory I/O
• A32 BLT read chained (AM 0x0B)

Register I/O

AM 0x29, A16 D32

Reg 0, @0x0000, Control, R/W

• [0] run enable
• [1] reset
• [2] CBLT readout enable
• [19:3] reserved
• [20] middle in chain
• [21] last in chain
• [22] first in chain
• [31:23] reserved

Reg. 9, @0x0024, Status, read-only

• [0] TTC clock locked
• [1] module Ok
• [2] subdevice 0 Ok
• [3] subdevice 1 Ok
• [4] subdevice 2 Ok
• [5] subdevice 3 Ok
• [6] subdevice 4 Ok
• [7] subdevice 5 Ok
• [31:8] reserved

Optional Registers

Reg. 3, @0x000C, JTAG, JTAG Serial Port

• [0] TDI/TDO
• [1] TMS
• [31:2] reserved

Reg. 8, @0x0020, JTAG32, JTAG Serial Port Block Mode

• [31:0] TDI/TDO

CR/CSR

AM 0x37, A24 D16

Reg. 0 @0x0000, CR0, read-only

• [15:8] vendor ID (constant 0xA6)
• [7:0] reserved (0)

Reg. 1 @0x0002, CR1, read-only

• [15:8] module ID

• [7:0] module serial number

Reg. 3 @0x0004, CSR, R/W

• [15:11] base address bits
• [10:0] reserved

Base address bits sets the following address bits:

• A16 - bits A15:A11
• A24 - bits A23:A19
• A32 - bits A31:A27

It is recommended to use geographical address GA4:GA0 as base address bits.
