To operate in the HBI Multiplexed mode, the following switch configurations in Table 3-6
must be enabled.
Along with the switch configuration, the following jumper configuration in Table 3-7
must be done for 8-bit/16-bit mode.
3.2.3 SPI/SQI Mode
The SPI/SQI Slave module provides a low pin count synchronous slave interface that
facilitates communication between the device and a host system. The SPI/SQI Slave
allows access to the System CSRs and the internal FIFOs and memories. It supports
single and multiple register read and write commands with incrementing, decrementing
and static addressing. Single-bit lanes are supported in SPI mode.
To select SPI/SQI Mode, configuration should be done as in
Table 3-8 .
3.2.3.1 SPI MODE CONFIGURATION
The following switches need to be configured as in Table 3-9 to enable the SPI mode
to communicate with the Explorer 16 Development Board.
Based on the plug-in boards on the Explorer 16 Development Board, [MA320003
(PIC32MX795F512L), MA240011 (PIC24FJ128GA010) or with MA320012
(PIC32MZxxxxECx100)] the following configuration in
Table 3-10 has to be done in
SW8.
