IA186EB/IA188EB
8-Bit/16-Bit Microcontrollers
Errata No. 8
Problem:
Description:
and bus hold
Workaround:
Errata No. 9
Problem:
The Relocation Register (RELREG, PCB offset 0xA8) can only be modified by an 8-bit write.
Description:
8-bit write. A 16-bit write will have no effect. The 186 EB is unaffected.
Workaround:
Errata No. 10
Problem:
When the timer compare register for any of the timers is set to x0000, the max count is xFFFF
instead of x10000 as in the OEM part.
Description:
is set to x0000.
Workaround:
Support if this erratum is an issue.
Errata No. 11
Problem:
NMI cannot bring chip out of powerdown mode.
Description:
with the PWRDN bit set in the PWRCON register.
Workaround:
Pin LOCK_n does not have an internal pullup.
.
Because Pin LOCK_n does not have an internal pullup, it will float during reset
The Relocation Register (RELREG, PCB offset 0xA8) can only be modified by an
The timer output will change one count earlier than it should when the max count
Only a reset brings the part out of powerdown after a HLT instruction is executed
An external pullup may be necessary if there is high external load on the signal.
Use an 8-bit access to affect the RELREG register.
The workaround is application dependent. Please contact Innovasic Technical
Use IDLE instead of PWRDN.
