CC3100MODBOOST: CC3100MODBOOST why do HIBn and IRQ pulse at 57hz?

Part Number: CC3100MODBOOST

Only have +3.3V and GND connected to CC3100MODBOOST.

Noticed that HIBn and IRQ pulse low for 90 usecs exactly in sync.

Pulses are at 57 hz.

Voltage level also is strange, 0 to 2V.

Why?????

Tried on 2 brand new boards, both the same.

Already re-flashed latest service pack on 1 board with EMUBOOST and it worked perfect.
