• Manufacturer Part Number: S80C188EB13
• Description: 8-Bit/16-Bit Microcontrollers
• Manufacturer: INNOVASIC [InnovASIC, Inc]

IA186EB/IA188EB
8-Bit/16-Bit Microcontrollers
Errata No. 12
Problem:
Illegal serial port modes do not match OEM part.
Description:
illegal encoding (0x5, 0x6, or 0x7), the Innovasic part acts as though it were in mode 4. The
OEM part acts as if it were in mode 1.
Workaround:
Errata No. 13
Problem:
Non-maskable interrupt (NMI) can be pre-empted by maskable interrupt.
Description:
cycles and an NMI is recognized, it could be pre-empted by a maskable interrupt.
Workaround: None.
Errata No. 14
Problem:
Ready signal may not be recognized in bus cycles with zero wait states.
Description:
normally has no wait states (Start register bits 3-0 == 0000), the ready signal may not be
recognized in time to extend the bus cycle.
Workaround: Set wait states to 1 or more if using ready to extend bus cycles.
When instruction execution unit is in Decode state for 2 or more consecutive
When a chip select is set to use the ready signal to extend a bus cycle that
If the mode bits of the serial control register (S1CON, S0CON) are set to an
Use a valid encoding for serial mode.
