FDEBUGcc Enter Debug Mode FDEBUGcc
Conditionally
Operation:
If cc, then enter debug mode.
Assembler Syntax:
FDEBUGcc
Description:
If the specified floating-point condition is true, enter Debug mode and wait for OnCE

commands. If the
specified condition is false, continue with the next instruction. Non-aware floating-point conditions set the
SIOP flag in the IER register and the UNCC bit in the ER register if the NAN bit is set.
"cc" may specify the following conditions:
Non-aware
Mnemonic Condition Set UNCC*
EQ - equal Z = 1 No
ERR - error UNCC v SNAN v OPERR v No
OVF v UNF v DZ = 1
GE - greater than or equal NAN v (N & ~Z) = 0 Yes
GL - greater or less than NAN v Z = 0 Yes
GLE - greater, less or equal NAN = 0 Yes
GT - greater than NAN v Z v N = 0 Yes
INF - infinity I = 1 Yes
LE - less than or equal NAN v ~(N v Z) = 0 Yes
LT - less than NAN v Z v ~N = 0 Yes
MI - minus N = 1 No
NE(Q) - not equal Z = 0 No
NGE - not(greater than or equal) NAN v (N & ~Z) = 1 Yes
NGL - not(greater or less than) NAN v Z = 1 Yes
NGLE - not(greater, less or equal) NAN = 1 Yes
NGT - not greater than NAN v Z v N = 1 Yes
NINF - not infinity I = 0 Yes
NLE - not(less than or equal) NAN v ~(N v Z) = 1 Yes
NLT - not less than NAN v Z v ~N = 1 Yes
OR - ordered NAN = 0 No
PL - plus N = 0 No
UN - unordered NAN = 1 No
Note: The operands for the ERR condition are taken from the ER register.
* See description of the UNcc bit in Section A.4.
CCR Condition Codes: Not affected.
