OS_ReadSysInfo 14

(SWI &58)

Use

The purpose of this call is to allow code to determine the number of IIC buses that are present in the system and are supported by OS_IICOp.

Notes

This call was introduced in RISC OS 5.21. For older versions of RISC OS 5 which do not support this call, it is permissible to determine the IIC bus count by using OS_Hardware to call HAL_IICBuses (HAL_IICBuses is normally for internal use only, therefore code which needs to know the bus count should prefer to use this SWI instead wherever possible).
