ADC reference voltage VREF-ADC (X500)
At interface X500, you can supply the reference voltage for the integrated
analog-to-digital converters of the netX 90 processor.

SPM Interface (X600)
The SPI interface (position
(1)
provides signals for connecting to a host
system (i.e. SPI master) and in fact represents a SPM via SPI interface.
The signals of the serial dual-port memory interface of the evaluation board
NRPEB H90-RE can be routed to the pin header X600 (12-pin). To activate
the SPM interface at X600, set the switches to
Serial port memory via pin
header
as documented in Table 24 on page 44.
The connector of this interface of the NRPEB H90-RE is a male pin header
with 2 rows of 8 pins each.
The pin assignment of pin header X600 is as follows:

This figure also shows the signal directions. At least the signals SPM_CLK,
SPM_CS#, SPM_MOSI und SPM_MISO and GND must be connected.
