The register is composed by the following fields: 

15..12

10..8 

RFU 

SD  RFU 

ARRE  MKTE  RFSL_MBIT  RFSL_LBIT  DE  LE  BE  RST 

RST  (RW) - Reset bit

: Reset  bit is used to erase all the log memory and reset all the memory  pointers and counters 

included the histogram bins. The value of the bit remain set until the reset operation is performed then it returns to 0. 
Default value is 0. 

BE (RW) - Button_Enable bit

: if the Button_Enable bit is set the  RT0005 button can be used to start and to stop the 

logging activity. Default value is 0. 

LE  (RW)  -  Logging_Enable  bit

:  Logging_Enable  bit  is  used  to  enable(1)/disable(0)  the  logging  activity.  If  the 

Button_Enable bit is set the Logging_Enable bit can be set/reset using the manual interface. Once stopped, the logging 
activity can be restarted only after the tag has been reset using the RST bit. Default value is 0. 

DE  (RW)  -  Delay_Enable  bit

:  Delay_Enable  bit  is  used  to  enable(1)/disable(0)  the  usage  of  the  SAMPLING_DELAY 

register.  If  enabled,  the  first  sample's  acquisition  is  done  SAMPLING_DELAY  second  after  the  start  of  the  logging 
activity. Default value is 0. 

RFSL (RW) - RF_Sensitivity_Level

: RF_Sensitivity_Level register is used to set the sensitivity level of the radio frequency 

front-end.  Sensitivity  can  be  set  on  3  different  levels:  3  =  maximum  sensitivity  level,  1  =  minimum  sensitivity  level. 
Default value is 1. 

MKTE    (RW)  -  Mean_Kinetic_Enable  bit

:  Mean_Kinetic_Enable  bit  is  used  to  enable(1)/disable(0)  the  Mean  Kinetic 

Temperature calculation. Default value is 0. 

ARRE  (RW)  -  Arrhenius_Enable  bit

:  Arrhenius_Enable  bit  is  used  to  enable(1)/disable(0)  the  calculation  of  the 

remaining Shelf Life (SHL_TIME) of the product using the Arrhenius equation with linear approximation. Default value is 
0. 

SD (RW) - Stop_Disable bit

: if the Stop_Disable bit is set the RT0005 button cannot be used to stop the logging activity. 

Default value is 0. 

 

SAMPLING_DELAY register (RW) 

Register 

Address 

Op. 

Default 

SAMPLING_DELAY 

0x0B 

RW 

0x0E10 

Sampling_Delay  register  defines  the  delay,  in  seconds,  of  the  first  acquisition  after  the  start  of  the  logging  activity. 
Register value range is 0 to 65535; default value is 3600 (seconds) corresponding to 1 hour delay. The sampling delay is 
activated if the corresponding bit on the CONTROL register (DE) is enabled.
