OBCB_StartA c [D>=19]

Start counting pulses on counting input c using the OnBoard Counter B (Firmware) counter. Counting will start when the OBCB time base is in phase A. If the time base is in phase A when the instruction is executed, counting starts at once. If it is in phase B, counting will start when it next enters phase A.

OBCB provides a medium speed counting feature on multiple inputs of selected controllers. Please refer to specific controller documentation for details as well as OBCB generic documentation.

Dialect exclusions: Not available in dialects before 19.

Note: At time of writing there is no simulation of the OBCA in SPLat/PC
