42.5.1.41 TBU1 watchpoint control 1 register (GTMDI_TBU1_WPC1)
The GTMDI_TBU1_WPC1 register shown in
TBU1 GTM Time Base Units. These watchpoints are used to control the requests for GTM
to enter Halt state, issue watchpoint messages and also to control logic external to the
GTMDI at SoC level such as in the SPU interface.
Note: Start/Stop signals inputs to the GTMDI can overwrite the state of the WMC1 and WMC2
control bits thus controlling the Watchpoint messages behavior. In case of JTAG modifies
the WMC1 or WMC2 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 from the GTMDI_TBU1_WPC2 register need to be set in order to allow external
Start/Stop signals to control the WMC1/2 bits.

Halt Enable 1. The HEN1 Halt Enable 1 bit controls if the TBU1 event is enabled to HALT the GTM
module. If this bit is set and an event occurs on the TBU1 a Halt signal is generated to the GTM

which enters debug state.
