Adjustment for 1.8V
Description of 1.8V calibration process
Text following “Command:” is the input command for the terminal connected to the CS.
Text following “Response:” is the terminal display response data.
Confirm the response before proceeding to the next step.If no response is set. shot off power and repeat from the beginning.
9.2.4.
Adjustment for RF Clock
Description of RF Calibration Process
Text following “Command:” is the input command for the terminal connected to the CS.
Text following “Response:” is the terminal display response data.
Confirm the response before proceeding to the next step.If no response is set. shot off power and repeat from the beginning.
Note:
Make sure to set all DIP switches OFF after adjustment of main part.
1) Measure BB1R8V voltage using a tester.
2) Send "VDD control adjustment" command.
Command: VDD xx XX ; 00 - 0FH
Response: OK Confirm BB1R8V voltage = 1.80V +/- 0.02V
3) Send "Read the adjustment value from the flash memory" command.
Command: VDD
Response: xx Confirm response xx = same as the adjustment value of 2)
1) Send "RF clock continuous output" command.
Command: RFC 1
Response: OK
2) Measure frequency RFCLK using a high impedance probe.
3) Adjust frequency using "RF clock adjustment" command.
Command: SFR xx XX ; 00 - FFH
Response: xx Confirm RFCLK frequency = 10.368MHz
±
10Hz
4) Send "Read the adjustment value from the flash memory" command.
Command: SFR
Response: xx Confirm response xx = same as the response of 3)
