DATASHEET
Bits 4 - 2 - CS_R2_IMIN[2:0] - Define the Custom IBUS_R2MIN threshold as shown in Table 10.40. The
default is 100 mA. This value is used under the following conditions: when a portable device
handshakes using the Legacy charger emulation profiles (except Legacy 2) or the Custom charger
emulation profile, or when it does not handshake in DCE Cycle (i.e., a power thief)). Under these
conditions, the current limiting mode is determined by the relative value of IBUS_R2MIN and ILIM. When
IBUS_R2MIN < ILIM or ILIM > 1.5 A, trip current limiting used; otherwise, CC mode is used.
Bits 1 - 0 - RESERVED - Do not change.
