The Fast Background Debug Mode (FBDM) module is a selectable
single-wire or multi-wire, background debug system implemented in
on-chip hardware for minimal CPU intervention.
This module is a super set of the BDM module and has added capability
for selection of an SPI type interface in addition to the single-wire
interface. This allows the interface to operate at a higher speed, through
the use of three pins.
• Single-wire communication with host development system
• Active out of reset in special single-chip mode
