TLU TTL I/O Control

• SDB Device ID 0xefa5e8d1

• Hardware: TLU40LVDS, TLU16SFP

• TLU40LVDS registers

Registers

• 00h - Identification 9e8cb63c, 32 bits, RO static

• 04h - Number of channels, RO static

Other registers: (Reg #+10) = TTL I/O #, R/W

• [14:0] - input or output selector
• [15] - output enable: 1 - output, 0 - input

Selector decode for inputs

• 0 - trigger
• 1 - veto
• 2 - ltr[0]
• 3 - ltr[1]
• 4 - ltr[2]
• 5 - ltr[3]

Selector decode for outputs

• 0 - accepted trigger
• 1 - rejected trigger
• 2 - busy
• 3 - TOF detector trigger
• 4 - luminosity detector trigger
• 5 - pulse per second (WR or Fe-Link)
• 6 - logic 0
• 7 - logic 1

For example:

• if

  • address = 0x11

  • data = 0x8004

• then

  • ttl[1] - output luminosity detector trigger
