BL4S100 User’s Manual

Blocks of digital output pins are associated with counters/timers on the Rabbit RIO chip.
Table 4 provides complete details for these associations.
Appendix D provides further details on the blocks and pins associated with the Rabbit
RIO chip to facilitate configuring each block consistently and to identify misconfigured
pins when a software function call returns a
Mode Conflict
error code.
Keep the following guidelines in mind when selecting special uses for the digital output
pins.
•
When using digital output pins for PWM/PPM outputs, the output pins can only share
the same RIO block if they are using the same period or frequency.
The
PWM.C
and the
PPM.C
sample programs in the
DIO
subdirectory in
SAMPLES\
BL4S1xx
show how to set up and use the PWM/PPM outputs.
