13. Continuous Wake Up Command Sending Test for the PICC Interface
This command is used for sending WUPA/WUPB by the reader continuously to test antenna field.
• Command = {E0 00 00 27 02 “Command” “Speed”}
• Disable Command Sending = { E0 00 00 27 02 00 00}
• Response = {E1 00 00 00 01 “Status”}
Command coding:
WUPA = 01
WUPB = 02
Speed coding:
106k bps = 00
212k bps = 01
424k bps = 02
Status:
WUPA Sending = 01
WUPB Sending = 02
Hints:
1. Make sure the Auto PICC Polling is disabled first before sending this command.
2. The reader will send the command continuously as long as the command starts. It can be stopped
by “E0 00 00 27 02 00 00”.
14. Read and Update the RC531 Register for the PICC Interface
• Read the Register APDU Command = {E0 00 00 19 01 “Register No”}
• APDU Response = {E1 00 00 00 01 “Current Value”}
• Update the Register APDU Command = {E0 00 00 1A 02 “Register No” “New Value”}
• APDU Response = {E1 00 00 00 00}
15. Go into Contactless EMV Terminal Loop
• Command = {0E 00 01 00 00}
• Response = {90“Current Value”}
16. Go into Contact EMV Terminal Loop
• Command = {0E 01 01 00 00}
• Response = {E1 00 00 00 01 “Current Value”}
17. Read and Initial Card Insert Counter
• Read the Register = {E0 00 00 09 00}
• Initialize the counter = {E0 00 00 09 04 “ICC Counter (LSB)” “ICC Counter (MSB)”
“PICC Counter (LSB)” “PICC Counter (MSB)”}
Response = {
E1 00 00 00 04 “ICC Counter (LSB)” “ICC Counter (MSB)” “PICC Counter
(LSB)” “PICC Counter (MSB)”}
• Update the counter data to static storage unit = {E0 00 00 0A 00}
