registers in the device. The microprocessor interface supports the fol-
lowing five modes:
MPU_SEL_CNFG[2:0] bits (b2~0, 7FH). The interface pins in different
interface modes are listed in
Table 34: Microprocessor Interface

After reset de-assertion, wait 10 us for the mode to be active.
Note 1: This pin is not used in this mode, this pin should be connected to ground
Note 2: This pin is open drain
The microprocessor interface provides access to read and write the
The microprocessor interface mode is selected by the
RDY (Note 2)
• EPROM mode;
• Multiplexed mode;
• Intel mode;
• Motorola mode;
• Serial mode.
