Figure 12-4. BDC Target-to-Host Serial Bit Timing (Logic 1)
Figure 12-5 shows the host receiving a logic 0 from the target MCU. Because the host is asynchronous to
the target, there is a 0-to-1 cycle delay from the host-generated falling edge on BKGD to the start of the
bit time as perceived by the target. The host initiates the bit time but the target finishes it. Because the target
wants the host to receive a logic 0, it drives the BKGD pin low for 13 BDC clock cycles, then briefly drives
it high to speed up the rising edge. The host samples the bit level approximately 10 cycles after starting
the bit time.
