see Additional Information: Phase Lock Loop for a description of
the PLL performance.

Also on page 6-14 the following figure should be added.

Figure 6-6A External Components for 4.192MHz

1. Missing Text.

On page 6-16, section 6.5.5.1, the following sentence should be added to the end of the
paragraph:

In the case where MODCK0-1 is 10, then SPCLK = EXTAL/128.

2. Error on Configuration Pins.

On page 6-19, Section 6.5.8, the last sentence states that the MODCK1-0 pins have an
internal pullup during reset. This is not correct and the sentence should be removed.

3. Missing Text.

On page 6-30, section 6.9.3.1, the note “SUPERVISOR ONLY” should appear below the
MCR register.
