TNPRM (1 byte)
TNPRM is an area to store various setting data related to timeout.
For more information about this parameter, see Section 7.3.3 Timeout.
Table 3-11 describes the TNPRM parameter.

„ QWT
QWT specifies the maximum wait time until the RFID receives a QUERY command from the host after it
sends an IRQ to the host during tunnel mode operation.
QWT is determined using the following formula.
Maximum wait time for QUERY command = T × 2^QWT
T: Typ. 1024 µs (±25%)
QWT: 0 to 8 (default: 4; typ. approximately 16 ms)
When this field is set to a value other than 0 to 8, a default value will be applied.
„ AWT
AWT specifies the maximum wait time until the RFID receives an ANSWER command from the host after it
sends a response to the QUERY command to the host during tunnel mode operation.
AWT is determined using the following formula.
Maximum wait time for ANSWER command = T × 2^AWT
T: typ. 1024 µs (±25%)
AWT: 0 to 12 (default: 7; typ. approximately 131 ms )
When this field is set to a value other than 0 to 12, a default value will be applied.
Note: T includes an error of ±25%. Set the QWT and AWT values in consideration of the error.
HW2 (1 byte)
HW2 is an area to store various setting data related to the hardware of this RFID.
Table 3-12 describes the HW2 parameter. INTWT and RESWT are parameters related to timeout in I2C
communication. For the setting of IRQSEL for IRQ notification, see Table 3-13.
