The ETM-A5 macrocell includes the following configuration inputs:
MAXEXTOUT[1:0] determines the maximum number of external outputs
MAXEXTIN[2:0] determines the maximum number of external inputs
MAXCORES[2:0] determines the number of processors that share the ETM.
TSMAXWIDTH determines whether the TSVALUE input is 64 or 48 bits wide
TSNATURAL determines whether the TSVALUE input is Gray coded or natural binary.
On an ETM-A5 implementation, these configuration inputs might be tied off to fixed values, or they might be available as configuration pins on the SoC.
For a description of bits [21:17] of the ETMCCR , see Configuration Code Register.
