IIOF interrupt
The firmware can generate pulses on the external interrupt lines of the TIM.
Only the interrupt line IIOF1 and IIOF2 are connected from/to the DSP and the
HOST.
• IIOF1 is connected from the DSP side to the HOST side: so, the DSP
interrupts the HOST
• IIOF2 is connected from the HOST side to the DSP side: so, the HOST
interrupts the DSP
The IIOF interrupt lines are described in the SMT6400 help file .
FPGA space availability
Latest firmware version is designed in VHDL following the model described in the
SMT6500 help file .
Depending on the FPGA fitted on board, two firmware versions are available:
• SMT365_32_2: Virtex-II 2000, 32-bit SDB interfaces
• SMT365_32_1: Virtex-II 1000, 32-bit SDB interfaces
