Retrieving
Measurements
Figure C-5 shows the conditions monitored to determine when measurements
are available in the data buffer.
Comments
•
The registers used are:
–
Status Register (base + 04
16
)
–
Data Buffer (base + 0C
16
)
•
Bit 4 is monitored to determine when a reading is in the Data Buffer.
•
In the four-byte reading mode, the Data Buffer must be read two
times for each reading. The first time the buffer is read, the upper
16 bits are retrieved. The second time the buffer is read, the lower
16 bits are retrieved.
•
In the two-byte reading mode (10
µ
s aperture time), the Data Buffer
is read one time for each reading.
•
The process is repeated until all readings have been read from the buffer.
