Figure 52. BSD I/O Hardware Interface
IO_VSS
BSD is a pulse-width modulated signal with three possible
?
When writing bits, user code toggles a GPIO pin and uses
states: sync, zero, and one. These are detailed, together with
their associated tolerances, in Table 96. The frame length is
19 bits and communication occurs at 1200 bps ± 3%.

the LHSCAP and LHSCMP registers to time pulse widths
and generate an interrupt when the BSD output pulse
width has reached its required width.

BSD COMMUNICATION HARDWARE INTERFACE
The ADuC7033 emulates the BSD communication protocol
using a GPIO, an IRQ, and the LIN synchronization hardware,
all of which are under software control.
BSD RELATED MMRS
ADuC7033 emulates the BSD communication protocol using a
software (bit bang) interface with some hardware assistance
form LIN hardware synchronization logic. In effect, the
ADuC7033 BSD interface uses the following protocols:
?
An internal GPIO signal (GPIO_12) that is routed to the
external LIN/BSD pin and is controlled directly by
software to generate 0s and 1s.
?
When reading bits, the LIN synchronization hardware uses

LHSVAL1 to count the width of the incoming pulses so
that user code can interpret the bits as sync, 0, or 1.
