T3:
Depends on the ECE status, data values and ECL port readout rate
(> 100 nsec per word).
ECE = 0 : T3 = 16 (> 100 nsec per word);
ECE = 1 and all or part of the data = 0 : T3 = 2 to 17
(> 100 nsec per word);
ECE = 1 and all data = 0 : T3 = 0 and the ECL port readout is
suppressed.
T4:
Depends on the CSR and CCE status.
CSR = 0 or (CSR = 1 and CCE = 0) : T4 = 0
(CSR = 1 and CCE = 1) : T4 = 2.3
µ
sec.
T5:
Depends on the CCE status, data values and CAMAC
readout rate (> 1
µ
sec per word).
CCE = 0 : T5 = 16 (> 1
µ
sec per word).
CCE = 1 and all or part of the data = 0 : T3 = 2 to 17
(1
µ
sec per word).
CCE = 1 and all data = 0 : the CAMAC sequential readout and LAM
are suppressed.
