AT89/83EB5114

How to Take Advantage of the Calibration Value
The coefficient stored on the stacked die allow to determine the conversion result the
AT8xEB5114 should have returned in case its Vref was exactly equal to 2.4V. In order to
determine it, a multiplication of the result of the conversion with the coefficient stored in
the stack, followed by a shift are sufficient.
Example
Vref is 2.36V instead of 2.4V, and only 8 bits are necessary.
The value measured during the test 2.36V. So, in accordance with the Table 47, the
coefficient which has to be stored on the EEPROM is 0x7e which corresponds to
0.1111110 in binary, which also corresponds to around 2.36/2.4.
If, for example, after a conversion, the ADDH register contains 0xf0, to know the result
the ADC should have returned in case the Vref was really at 2.4V, the following opera-
tions are necessary:
0xf0 * 0x7e = 1111 0000 * 0111 1110 = 0x7620 = 0111 0110 0010 0000.
So because of the point on the coefficient, the result is 1110 110 which is 0xec.
Assembler code example
This is an example of assembler code optimized for size and fast recalculation in case 8
bits are sufficient.

The new result is stored on the accumulator.
This routine requires 15 bytes + 3 bytes for the long call (LCALL).
The execution of the subroutine (including the LCALL) is 18 cycles in normal case and
19 cycles in case of overflow (less than 10us with a 12 MHz oscillator and the X2 mode).
