IIOF Connectivity

Each TIM site provides 3 interrupt pins, IIOF0, 1 & 2.
IIOF0 & 1 are connected in a daisy-chain with TIM site 1 IIOF0 connected to TIM site
2 IIOF1; TIM site 2 IIOF0 connected to TIM site 3 IIOF1 finishing with TIM site 4
IIOF0 connected to TIM site 1 IIOF1.
All TIM site’s IIOF2 signals are connected together.

FPGA configuration

In the default configuration the FPGA is configured by the microcontroller that fetches
the configuration in the flash device. However it is possible to download a new
configuration to the FPGA using the Xilinx JTAG cable connected to a PC and to JP5
on the SMT148 carrier. The pinout is as follow:

1 3.3V

2 GND

3 TMS

4 TCK

5 TDI

6 TDO
