Decrement CNT1
External Debug Action
No External Debug Action caused
Cause an External Debug Action (breakpoint pin etc.)
Entry Point Control
Set the PC to channel program Start. EP = 0 assumes that a
Channel Entry Table exists in the base of CMEM. Failure to
provide such a table will cause improper operation.
Set the PC to the address contained in NextPC (next
instruction) address.
Interrupt Control
No Interrupt
INT = 1 AND (cc_B = True) means Issue Interrupt
Action on Debug Exit
Stop channel program from accepting new service requests
(clear R7.CEN)
Allow further channel program execution and decrement PC
(so that DEBUG instruction is re-executed on next invocation)
Note: This field has no effect if SDB = 0 (see below)
Test Bit Control
Check for Clear (0)
Check for Set (1)
Stop on Debug
Continue running if debug event triggered
Stop PCP if debug event triggered
