Debug Abort Generate Register (DBGABORT)
DBGABORT is a word-wide write-only register, used to generate an ABORT. A processor may generate an ABORT to a
processor with a PID index of i by modifying its P_i bit to 1. Writing 0 to P_i does not result in ISE assertion. The register
format is shown below.
Location: 00 FDE8
Type:
Debug ISE Source Registers A (DBGISESRCA)
DBGISESRCA is a word-wide read/write register that indicates the ISE sources. The register is cleared on reset. Writing 1
to a bit in this register clears it. Writing 0 to a bit does not change its value. The DBGISESRCA register format is shown
below.

RX_i. The ISE source is the Rx data link. Turn on with ISE assertion. Turn off by writing a byte to DBGISESRC
containing 1 in the RX_i bit location.
0: Not an ISE source (default)
1: The ISE source is the Rx data link
ABORT_i. The ISE source is an ABORT request by the debugger or one of the processors. This bit is set by
either an abort command from the debugger (SCAN_RX with PID=‘1111’) or by a write of a 1 to the processor’s
respective bit in DBGISECA register.
0: Not an ISE source (default)
1: The ISE source is an ABORT event
