Calibration Status Register (CSR)
The Calibration Status Register (
CSR
) indicates calibration errors, if any, have occurred. Its bits and the
errors that set them, are as follows:
• State Indicators (Bits 7 and 6): The Bits 7/6 are set as follows:
00
– Normal Run Mode, set when the TempScan/1100 or MultiScan/1200 unit is in the state of
normal operation.
01
– EEPROM Test Mode, set when testing a scanning card EEPROM (Electronically Erasable,
Programmable Read-Only Memory). This internal mode will not be discussed in this manual.
10
– Calibration Mode (Idle), set when the TempScan/1100 or MultiScan/1200 unit is in idle
Calibration Mode.
11
– Calibration Mode (Command Active), set when the TempScan/1100 or MultiScan/1200 unit
is in active Calibration Mode.
• Error Indicators (Bits 0 to 5) in Normal Run Mode (00): Any calibration error in any of the four
modes will be mapped into the
CSR
Bits 0 to 5, which together maps to the Calibration Error Bit (Bit 3)
in the Error Source Register (
ESC
). In this normal mode, these six bits are set as follows:
Bit 5: Read Failure.
Bit 4: Write Failure.
Bit 3: Checksum Error.
Bit 2: NV-RAM Error.
Bit 1: Invalid Password.
Bit 0: Invalid Command.
