mode after the instruction is complete. Figure 10 shows

the related timing characteristics.

Enable any interrupt to clear PCON.0 and exit the Idle

mode (See Figure 11 for the related timing). Assert RST

alternately.

Stop Mode

In stop mode, the internal clock and analog circuitry are

powered-down. Set PCON.1 (STOP) HIGH to enter the

Stop mode after the instruction is complete. Figure 12

shows the related timing characteristics. The only way

to exit Stop mode is to assert RST.

Definitions

Integral Nonlinearity (INL)

Integral nonlinearity is the deviation of the values on an

actual transfer function from a straight line. This straight

line can be either a best straight-line fit or a line drawn

between the endpoints of the transfer function, once

offset and gain errors have been nullified. The static lin-

earity parameters for the MAX7651/MAX7652 are mea-

sured using the best straight-line fit method.
