Note: Start/Stop signals inputs to the GTMDI can overwrite the state of the DMC control bit thus
controlling the Data Trace messages behavior. In case of JTAG modifies the DMC bit and
Start/Stop signals occur at the same time also modifying the same bit, Start/Stop signals
have precedence over JTAG writes. The SEN control bit from the GTMDI_DPLL_DTC
register need to be set in order to allow external Start/Stop signals to control the DMC bit.

RAM Address Compare. The RAM_ADDR[11:0] field defines the address value that is
compared against the address for write and read DPLL RAM accesses. Before the
comparison is executed the RAM_ADDR_MASK should be considered thus masking
corresponding bits. A masked bit is always considered a match.
Note: DPLL module has three RAM modules with different address widths. The address
value in the RAM_ADDR field and the RAM address should be right aligned in order
to be compared.
