Zigbee/IEEE802.15.4 MC13192evb code development

In the 802.15.4 MAC/PHY SoftwareReference Manual (802154MPSRM.pdf)

I read :

5.3.1void Asp_GetTimeReq(zbClock24_t *time)

This function requests the current value of the transceiver internal event timer.

The time pointer points to a 3 byte array where the value of the transceiver’s internal 24 bit event timer will be copied. The current value of the internal event timer (0x000000 to 0xFFFFFF) is a little endian byte array. The function does not return any value because the call is always successful.

What are the granularity and resolution of the current time returned with *time?

Hi,

the Clock are setup to run based on the "symbol" time that 802.15.4 uses.

this is 16uSec per symbol.

e.g

5 second are: 5E-6 / 16 = 0x04c4be

BR,
