Chapter 17: SPI Controller
Slave Mode via MIO
17.5.5 MIO/EMIO Signal Tables
The SPI I/O interface signals routing has some options. The routing options include multiple
positions in the MIO pins. The options are illustrated in section 2.5.4 MIO-at-a-Glance Table and in
Table 17-5.
Default Input Signal Routing: If the I/O signals are not routed to a set of MIO pins (MIO_PIN_xx
register programming), then the EMIO interface input signals are enabled.
MIO Pin Limitation
Small Package Note: The MIO pin restrictions based on device version are shown in the MIO table
in section 2.5.4 MIO-at-a-Glance Table. Each SPI I/O interface is selected as a group.
