Function

CPU may be halted if a conditional jump is followed by a rotate PC instruction

Description

If a conditional jump instruction (JZ, JNZ, JC, JNC, JN, JGE, JL) is followed by an Address Rotate instruction on the PC (RRCM, RRAM, RLAM, RRUM) and the jump is not performed, the CPU is halted.

Workaround

Insert a NOP between the conditional jump and the rotate PC instructions.
