CCx Threshold Match (CCx_MATCH)

When set, each bit indicates that the respective threshold programmed in the

CC Threshold x Registers (CC_THRx) was matched. A match is determined

when the measured voltage exceeds the programmed threshold.

These registers are updated after the Match Debounce Register

(MATCH_DEB) while in the Unattached state. While in AttachWait state,

these registers are updated after the PD Debounce Register (PD_DEB) if

vOpen is seen for a time greater than in the PD Debounce Register

(PD_DEB). While in Attached Source / Attached Sink states (e.g. detecting

detach) the match registers are updated after the PD Debounce Register

(PD_DEB).

Note:

This register will always read the default value until the CC com-

parator is enabled when not operating in standalone mode.

Note:

The contents of this register are debounced per the settings in the

CCx Debounce Clear Enable Registers (CCx_DBCLR_EN), other-

wise the raw value shall be shown.
