42.5.1.25 ARU watchpoint DATA1L register (GTMDI_ARU_DATA1L)
The ARU Watchpoint DATA1L low word shown in
against the low word of the ARU Debugging Channel 1. The address for the channel to be
monitored is defined by the Host CPU in the GTM IP ARU_DBG_ACCESS1 register.

42.5.1.26 ARU data trace control register (GTMDI_ARU_DTC)
The GTMDI_ARU_DTC register shown in
transmission. The GTM Module selects two ARU addresses to be monitored, using the ARU
Debugging Channels 0 and 1. The data trace for these two channels is controlled by
DMC1/2 bits in this register. Once enabled, messages are generated as soon as a valid
data is identified in one of the ARU Debugging Channels, 0 or 1.
Note: Start/Stop signals inputs to the GTMDI can overwrite the state of the DMC1 and DMC2
control bits thus controlling the Data Trace messages behavior. In case of JTAG modifies
the DMC1 or DMC2 bits and Start/Stop signals occur at the same time also modifying the
same bits, Start/Stop signals have precedence over JTAG writes. The SEN1 and SEN2
control bits need to be set in order to allow external Start/Stop signals to control the DMC1/2
bits.
