MAJOR OPERATING MODES
The DS33Z11 has three major modes of operation: microprocessor controlled, EEPROM initialized, and
Hardware mode.
Microprocessor control is possible through the 8-bit parallel control port. More information on microprocessor
control is available in Section 8.1.
EEPROM initialization is enabled by the built-in SPI master that reads a serial EEPROM connected to the SPI
port after device reset and initializes the device. More information on EEPROM operation is available in Section
8.2.
Hardware mode allows configuration of the device without a host microprocessor or EEPROM. More information
on Hardware mode is available in Section 8.20.
