Active Errata List
Errata History
Errata Description
1. EEPROM – EEPROM Data Cannot be Accessed from the Boot Area (FM1)
2. XRAM – P3.7 and P3.6 Signals are Generated
3. Double IT on External Falling Edge On INT1 or INT0 in X2 Mode
4. Timer 2 (Baud Rate Generator Mode) – No IT When TF2 is Set by Software
Lot Number
A00470
A01013 and above
EEPROM Data cannot be read or written from the boot area (FM1).
Workaround
None.
When an overflow access is detected on the XRAM during a Movx instruction,
negative pulses on the P3.7 and P3.6 signals are generated.
Workaround
None.
When CPU is in X2 Mode and Timer 1 or Timer 0 in X1 Mode (CKCON = 0x7F),
IEx flag is not cleared by hardware after a service interrupt. In this case, the CPU
executes the ISR a second time.
Workaround
The work around is to clear IEx bit during the Interrupt subroutine.
INT1_ISR :
When Timer 2 is used in baud rate generator mode, setting TF2 does not gener-
ate an interrupt.
Workaround
None.
Timer 2 (Baud Rate Generator Mode) – Long Start Time
UART – RB8 Lost with JBC on SCON Register
CAN – CANCONCH Harmless Corruption
ADC – Interrupt During Idle Conversion
Flash/EEPROM – First Read After Load Disturbed
CAN – Sporadic Errors
C51 Core – Bad Exit of Power-down in X2 Mode
Timer0/1
Timer1 - Mode1 Does Not Generate Baud Rate Generator for UART
Transmission after a 3 bit Intermessage
Extra interrupt
