UCC5870-Q1: STP_FAULT when changing ASC_EN state

Part Number: UCC5870-Q1

We are using the UCC5870-Q1 and are getting an STP_FAULT [STATUS2 bit 11] when changing the ASC_EN state.

The scenario occurs when:
* ASC_EN is at a high level
* ASC is at a low level
* IN+ is at high level
* IN- is at a low level
* then change the ASC_EN to a low level and the STP_FAULT bit will be set

Is this expected behavior?

Here are our register settings:
CFG1 = 0x1C0F
CFG2 = 0x0200
CFG3 = 0x0020
CFG4 = 0x1B5C
CFG5 = 0x7941
CFG6 = 0x0308
CFG7 = 0xA2D0
CFG8 = 0x0008
CFG9 = 0x8140
CFG10 = 0xC00C
CFG11 = 0x0000
ADCCFG = 0x0D0D
DOUTCFG = 0x0000
