Known limitations
Doc ID 14952 Rev 4
13.1
STM8A core
13.1.1
Wait for event (WFE) instruction not supported
Description
The WFE instruction is not implemented in devices covered by this datasheet. The WFE
instruction is used to synchronize computing resources and not relevant for the present
implementation. For further details on this instruction, refer to the STM8 CPU programming
manual (PM0044) on www.st.com.
Workaround
None.
13.1.2
JRIL and JRIH instructions not supported
Description
JRIL (jump if port INT pin = 0) and JRIH (jump if port INT pin = 1) are not supported in
devices covered by this datasheet. If implemented, they are conditional jumps: JRIL jumps if
one of the external interrupt lines is low and JRIH jumps if one of the external interrupt lines
is high.
In the devices covers by this datasheet, JRIL is equivalent to an unconditional jump and
JRIH is equivalent to NOP. For further details on these instructions, refer to the STM8 CPU
programming manual (PM0044) on www.st.com.
Workaround
None.
13.1.3
CPU not returning to HALT if the AL bit is set
Description
When the AL bit of the CFG_GCR register is set, the CPU does not return to HALT mode
after exiting an interrupt service routine (ISR). It returns to the main program and executes
the next instruction after the HALT instruction.
Workaround
None.
13.1.4
Main program not resuming after ISR has resets the AL bit
Description
If the CPU is in wait for interrupt state and the AL bit is set, the CPU returns to the wait for
interrupt state after executing an ISR. To continue executing the main program, the AL bit
must be reset inside the ISR. When AL is reset just before exiting the ISR, the CPU may
remain stalled.
Workaround
The AL bit has to be reset at least two instructions before the IRET instruction.
