function QEMUVPBClockGetCount:LongWord;
Description: Gets the current system clock count (32 least significant bits of total)
| Note | On the VersatilePB this comes from the 24MHz counter which will overflow every 178 seconds |
|---|
function QEMUVPBClockGetTotal:Int64;
Description: Gets the total system clock count
| Note | On the VersatilePB this comes from the 24MHz counter which will overflow every 178 seconds and increment the rollover value. This is only accurate if either ClockGetCount or ClockGetTotal is called at least once per 178 seconds on order to increment the rollover. |
