Problem:
Description:
opcode of the form 1111_0111_1100_0xxx, the Program Counter could become corrupted upon

Workaround:
Errata No. 7
Problem:
memory.
Description:
Workaround:
Timer 2 will stop or not start counting.
Write does not occur when counter is actively counting.
Program Counter can become corrupted if an interrupt occurs.
Bound instruction uses bad data when index addresses are on odd boundary in
Writing a logic ―1‖ to unused bits in the timer control register can cause the timer
If a timer incremented its count register to the currently active compare register
If an interrupt occurs during the decode stage of a TEST instruction using an
BOUND instruction will use bad data if index address LSB is a ―1‖ in memory.
Do not write a logic ―1‖ to any unused or reserved bits in the timer control
Do not write count register while that counter is actively counting.
None.
None.
