Errata No. 4
Problem: Timer 2 will stop or not start counting.
Description: Writing a logic ―1‖ to unused bits in the timer control register can cause the timer
to stop counting or to never start counting.
Workaround: Do not write a logic ―1‖ to any unused or reserved bits in the timer control
register.
Errata No. 5
Problem: Write does not occur when counter is actively counting.
Description: If a timer incremented its count register to the currently active compare register
during a write to that count register, the write would not occur.
Workaround: Do not write count register while that counter is actively counting.

Description: If an interrupt occurs during the decode stage of a TEST instruction using an
opcode of the form 1111_0111_1100_0xxx, the Program Counter could become corrupted upon
returning from the interrupt handler.
Workaround: None.
