Other Interfaces
20.5.2. IIC Bus
The module provides one I2C bus. The master mode is available up to 400kbit/s.
20.6. PCM Function
Digital audio interface mode allows connectivity with standard audio peripherals.
IOM-2 compatible device on physical level.
20.7. External Interruptions Function
The module provides nine external interruptions.
Note:
Only three interruptions are indicated on the Development Kit. The others external interruptions are
hidden through multiplexed GPIOs.
Table 19 displays the external interruption signals.

20.8. Parallel Bus Function
With the module, it is possible to interface applications with a 16 bits parallel bus with a few addresses
and chip select signals (LCD, NAND FLASH, µ
P…), as listed below. All signals are in 1.8V.
20.8.1. Configuration Constraints on the External Board
Connector (J1100)
These signals are available on the TP and the external board connector (J1100).
The possible configurations with the constraints of the multiplexed signals are:
CS3*, A1, GPIO1, GPIO2
CS3*, A1, A24, GPIO1
CS3*, A1, A24, A25
CS3*, CS2*, A1, GPIO2
CS3*, CS2*, A1, A24
(*): Signal is active at the low level.
Please refer to document [2] for multiplexing software configuration supported.
