Missing sync word in SPI comunications

Other Parts Discussed in Thread: CC3100

Hi all,

we are working with CC3100 module and SPI with SDK 1.2 and ServicePack_1.0.1.6-2.6.0.5. After some message CC3100 stop answer correct sync sequence

as shown host correctly send 65877856, to ack Irq. So module deassert IRQ line, but the module don't send correct BDDCCDAB sync word.

Any idea ?
