DL_Common_delayCycles()

void DL_Common_delayCycles

(

uint32_t

cycles

)

Consumes the number of CPU cycles specified.

Parameters

[in]

cycles

Floor number of cycles to delay. Specifying zero will result in the maximum possible delay. Note that guarantees at least this number of cycles will be delayed, not that exactly this number of cycles will be delayed. If a more precise number of cycle delay value is needed, GPTimer is recommended.

Typical variance from this function is 10 cycles or less assuming that the function is located in flash and that caching is enabled. Disabling caching may result in wait-states when fetching from flash. Other variance occurs due:

• Amount of register stacking/unstacking around API entry/exit
• Value of cycles relative to 4-cycle loop counter
• Placement of code on a 2- or 4-byte aligned boundary
