UNCONFIRMED  errors and comments from readers: 

[safari 13.12, 256-257 in printed text]  Figure 13-36, following 3rd paragraph; also 4th paragraph;

Figure 13-36 shows the MC33298 used as a "high side" switching device. However the
Freescale datasheet describes it as a "low side power switch".

Given this, the fourth paragraph has a corresponding error. Activating a switch does
not connect the load to Vpwr (which is the MC33298's MOSFET gate drive supply) but to
ground. So the text, "When a given switch is activated, the corresponding output is
connected to the VPWR supply..." should be changed to "...the corresponding output is
connected to ground..."


(278) Figure 15-1;
In figure 15-1, the AVR processor register diagram indicates that the register pairs R26:R27, R28:R29, and R30:R31 make up the X, Y, and Z 16-bit registers. However, the text which indicates this reads "X-register low byte" (for example) for both registers. Obviously one or the other of the registers must be the high byte of the 16-bit register.
