MAX11301 Datasheet, PDF (29/55 Pages) Maxim Integrated Products – Programmable Sample Averaging Per ADC Port

MAX11301
PIXI, 20-Port Programmable Mixed-Signal I/O with
12-Bit ADC, 12-Bit DAC, Analog Switches, and GPIO
the third byte has been fully received. A burst transaction
would simply be the extension of the single register trans-
action, where the address is automatically incremented
from one data word to the next (Table 4 and Table 5).
Each time a new data sample is read or written, the
register address is incremented by one until it reaches the
last register address. The RESTART shown in Tables 3
and 5 could be replaced by a STOP followed by a START.
If a transaction targets an unused address, nothing is
written within the MAX11301 for write transactions, and
all zeros are read back for read transactions. Similarly, if
a write transaction targets a read-only register, nothing is
written to the device.
