*** 24 CALIBRATION ***

FUNCTION

Put 19 calibration values into input locations. If C (--) is keyed before entering the input location, then the automatic calibrations are simply displayed, not measured. Otherwise, the calibration takes place only when Instruction 24 is executed; automatic calibration is disabled (Section 13.7).

*** 25 PORT READ ***

FUNCTION

The status of a group of ports selected by a mask is read and placed in an input location. The status is a base 2 representation of the ports converted to base 10. Port 1 is the least significant bit. For example, if all ports are read, and the port status is as follows:

PORT

C8

C7

C6

C5

C4

C3

C2

C1

(0=low,

 

 

 

 

 

 

 

 

1=high)

 

 

 

 

 

 

 

 

Base 10 equivalent: 32 + 16 + 2 = 50 50 will be stored in the input location.

The mask is also base 2 representation; 1 indicates the port is to be read, 0 results in a 0 for the port regardless of the status of the port (AND operation). For example, if 50 (see above example) is entered for the mask, ports 2, 5, and 6 are read. If only ports 4 and 5 are high, the status will be 16 (port 4 is not read).
