UJA116xA evaluation boards

2.5 MCU interface

The digital interface pins are located on the top side header J3 (J3-01 to J3-06), as well

as on the bottom side connector J4. Two of these pins, TXD and RXD, are used for CAN

data communication with the MCU. The remaining pins are used for communication with

the MCU, either as SPI signals (see 

Table 10

) or as simple control and status signals

(see 

Table 11

).

2.5.1 CAN TXD/RXD and SPI connections (UJA1164A/68AF/68AXF-EVB)

For variants with an SPI interface (UJA1164A, UJA1168A), integrated Multiple Time

Programmable Non-Volatile (MTPNV) memory cells allow the device to reload previously

configured settings at power up. The device boots up in Forced Normal mode when not

previously configured. Factory preset values can be restored if certain conditions are

met.
Detailed information on the functionality and operation of the UJA1164A and UJA1168A

can be found in the data sheets and application hints (see 

Section 7

).
