Portable_Speed2 0

(SWI &42FCE)

Use

The purpose of this call is to read the current CPU speed, in MHz. To instead read the CPU speed index, use Portable_Speed2 7.

Notes

There is no direct method available to set the CPU speed to a desired value. Instead programs must use Portable_Speed2 2 (or Portable_Speed2 8) to set the desired ‘slow’ and ‘fast’ speeds, and then Portable_Speed to switch to the desired speed.
