(9) On-chip debugging option byte setting (address C3H)
The on-chip debugging option byte setting is rewritten arbitrarily by the debugger.
(10) FLMD0 pin output status while debugger is running
In accordance with the setting in the Flash Programming area in the Configuration dialog box of the debugger,
the FLMD0 pin output status while the debugger is running changes as follows. Rewriting by flash
self-programming is not possible when the output status is low level.
- When Permit is selected: High level (low level for about 100
µ
s after reset release)
- When Not Permit is selected: Low level
(11) Operation at voltage with which flash memory cannot be written
Do not perform the following operations at a voltage with which flash memory cannot be written. Otherwise,
the subsequent operation may be unstable.
<1> Writing to internal flash memory
<2> Setting or canceling of software breakpoint
<3> Starting execution at the set software breakpoint position
<4> Step execution at the set software breakpoint position
<5> Step-over execution, Return Out execution
<6> Come Here
<7> If Permit is selected in the Flash Programming area in the Configuration dialog box, the following
operations cannot be performed.
a) Setting, changing, or canceling of hardware breaks
b) Masking/unmasking of internal reset
c) Switching of peripheral breaks
