ATmega128RFA1
This register contains the second most significant byte of the 32 bit Frame (SFD)
Timestamp Register
• Bit 7:0 – SCTSRHL7:0 - Symbol Counter Frame Timestamp Register HL-Byte
This register contains the second least significant byte of the 32 bit Frame (SFD)
Timestamp Register
• Bit 7:0 – SCTSRLH7:0 - Symbol Counter Frame Timestamp Register LH-Byte
This register contains the least significant byte of the 32 bit Frame (SFD) Timestamp
Register
• Bit 7:0 – SCTSRLL7:0 - Symbol Counter Frame Timestamp Register LL-Byte
This register contains the most significant byte of the 32 bit Beacon Timestamp
Register. The Beacon Timestamp Register is updated with the contents of the Frame
Timestamp Register if the received frame was a valid beacon frame with matching
source PAN identifier or register {PAN_ID_1, PAN_ID_0} = 0xFFFF.
