FUNCTIONAL DEVIATIONS
Deviation #1
RxD1 pin is an open drain configuration.
Work-around:
A resistor must be used if this pin is to be used as an output. These pins will become port 4 on the next
release fixing this issue.
Deviation #2
Port 4 does not exist for the RxD1 and TxD1 pins. DC parameters differ from standard port pins.
Work-around:
None. These pins will become port 4 on the next release.
Deviation #3
RxD1, TxD1, and ALE pins will not go into once mode.
Work-around:
None. This will be fixed on the next release.
Deviation #4
In the UART, the contents of RB8 and SBUF change when they shouldn’t if SM2=1 in modes 2 and 3.
Work-around:
None. Will be fixed on the next release.
Deviation #5
The UART double buffering will be implemented on the next release.
Work-around:
None.
Deviation #6
SPI block will be implemented on the next release.
Work-around:
None.
Deviation #7
Security bits are not 100% compatible with past 80c51 products.
Work-around:
The security bits will be compatible on the next release.
