Section 6 Instruction Descriptions
6.3.20
Format
PSUB Sx,Sy,Dz
DCT PSUB
Sx,Sy,Dz
DCF PSUB
Sx,Sy,Dz
Description: Subtracts the contents of the Sy operand from the Sx operand and stores the result in
the Dz operand. When conditions are specified for DCT and DCF, the instruction is executed
when those conditions are TRUE. When they are FALSE, the instruction is not executed.
When conditions are not specified, the DC bit of the DSR register is updated according to the
specifications for the CS bits. The N, Z, V, and GT bits of the DSR register are updated. If
conditions are specified, the DC, N, Z, V, and GT bits are not updated even is the conditions were
true and the instruction was executed.
