Boot configuration pins are:
● PAD A[2] - ABS[0],
● PAD A[3] - ABS[1],
● PA D A [ 4 ] - FA B
Note: PAD A[2] - ABS[0] is not bonded on SPC560P40/34 64-pin LQFP package so for this
package the option 'FlexCAN without Autobaud ' is not available and the internal pull-down
on PAD A[2] assures that it is at low logical value at reset.

The TX/RX pin (LINFlex_0 and FlexCAN_0) used for serial boot and configuration boot pins
to select the serial boot mode are described in the Ta ble 4 3 6 for 64-pin and 100-pin LQFP
packages.
