STATUS REPORTING COMMANDS
The Status Byte definitions follow this section.
❊CLS The ❊CLS command clears all status registers. The status enable regis-
ters are NOT cleared.
❊ESE (?) {i} {,j} The ❊ESE i command sets the standard event enable register to the
decimal value i (0-255). The ❊ESE i,j command sets bit i (0-7) to j (0 or
1). The ❊ESE? command queries the value (0-255) of the status byte
enable register. The ❊ESE? i command queries the value (0 or 1) of bit i.
❊ESR? {i} The ❊ESR? command queries the value of the standard event status
byte. The value is returned as a decimal number from 0 to 255. The
❊ESR? i command queries the value (0 or 1) of bit i (0-7). Reading the
entire byte will clear it while reading bit i will clear just bit i.
❊SRE (?) {i} {,j} The ❊SRE i command sets the serial poll enable register to the deci-
mal value i (0-255). The ❊SRE i,j command sets bit i (0-7) to j (0 or
1).The ❊SRE? command queries the value (0-255) of the serial poll
enable register. The ❊SRE? i command queries the value (0 or 1) of bit i.
❊STB? {i} The ❊STB? command queries the value of the serial poll status byte.
The value is returned as a decimal number from 0 to 255. The ❊STB? i
command queries the value (0 or 1) of bit i (0-7). Reading this byte has
no effect on its value.
❊PSC (?) {i} The ❊PSC command sets the value of the power-on status clear bit. If
i=1 the power-on status clear bit is set and all status registers and enable
registers are cleared on power up. If i=0 the bit is cleared and the status
enable registers maintain their values at power down. This allows a ser-
vice request to be generated at power up.
ERRE (?) {i} {,j} The ERRE i command sets the error status enable register to the deci-
mal value i (0-255). The ERRE i,j command sets bit i (0-7) to j (0 or 1).
The ERRE? command queries the value (0-255) of the error status
enable register. The ERRE? i command queries the value (0 or 1) of bit i.
ERRS? {i} The ERRS? command queries the value of the error status byte. The
value is returned as a decimal number from 0 to 255. The ERRS? i com-
mand queries the value (0 or 1) of bit i (0-7). Reading the entire byte will
clear it while reading bit i will clear just bit i.
LIAE (?) {i} {,j} The LIAE command sets the lock-in (LIA) status enable register to the
decimal value i (0-255). The LIAE i,j command sets bit i (0-7) to j (0 or 1).
The LIAE? command queries the value of the LIA status enable register.
The LIAE? i command queries the value (0 or 1) of bit i.
LIAS? {i} The LIAS? command queries the value of the lock-in (LIA) status byte.
The value is returned as a decimal number from 0 to 255. The LIAS? i
command queries the value (0 or 1) of bit i (0-7). Reading the entire byte
will clear it while reading bit i will clear just bit i.
