MPD TRC Trigger

Registers are 16 bit width. 32-bit and 64-bit data is packed as following:

Registers map

• 00h - Identification 8a3b62cd, 32 bits, RO static

• 04h - Number of input channels, RO static

• 05h - Number of physical triggers, RO static

• 08h - FHCAL East logic code, R/W

  • [1:0] input logic: '0' - common OR, '1' - common AND, '2' - majority
  • [15:8] threshold for majority logic

• 09h - FHCAL West logic code, R/W

  • [1:0] input logic: '0' - common OR, '1' - common AND, '2' - majority
  • [15:8] threshold for majority logic

• 0Ah - FHCAL Output logic code, R/W

  • [0] FHCAL output logic: '0' - OR between East-West, '1' - AND between East-West

• 40h~7Fh - Input shapers values, R/W

  • one register - one input channel
  • actual number of registers read from register 04h (number of input channels)

• 80h~CFh - Input delays values, R/W

  • one register - one input channel
  • actual number of registers read from register 04h (number of input channels)

• 100h~1FFh - LUTs for physical triggers, R/W

  • Number of words for LUT depends on number of physical triggers PHY_NCH (reg 05h: if PHY_NCH is 4 of less, then number of LUT words is 1, else use equation 2^(PHY_NCH-4)
