Overview of the Apollo4 Display Kit
The Apollo4 Plus Display Kit consists of two PCB assemblies:
1.
The Apollo4 Plus EVB (AMAP4PEVB), revision 2 or later
2.
The Apollo4 Plus Display Shield revision 1
Please note that the Apollo4 Plus Display Kit is only compatible with the (non-blue) Apollo4 Plus EVB, part
number AMAP4PEVB.
The combined features of the two-board assembly are shown in the block diagrams of Figure 2 and
Figure 3. When MSPI0 is used in hex mode (16-bit interface), MSPI1 cannot be used, as the MSPI0 upper
data lines use the same pins on the Apollo4 Plus that MSPI1 uses. An Apollo4 Plus GPIO pin, GPIO34, is
used to select between using this set of pins as MSPI1 connections or as the upper data lines of MSPI0 in
hex mode.
Figure 2 represents the two-board assembly's feature set when connected to the APS256XXN PSRAM
device over MSPI0 in hex mode. MSPI1 is not used in this configuration.
