DATASHEET

regardless of the reason, then the Custom charger emulation profile will accepted. If the portable

device does not draw more than IBUS_CHG current, then the UCS1002 will continue waiting until

this bit is cleared.

Bits 4 - 3 - CS1_EM_TIMEOUT[1:0] - Determines the tEM_TIMEOUT value, as shown in Table 10.24,

that is used when the Custom charger emulation profile is used during the DCE Cycle.

Bit 2 - CS1_FIRST - Determines whether the Custom charger emulation profile is placed first or last

in the DCE Cycle.



‘0’ (default) - The Custom charger emulation profile is the last of the profiles applied during the

DCE Cycle.



‘1’ - The Custom charger emulation profile is the first of the profiles applied during the DCE Cycle.

Bit 1 - RESERVED - Do not change. This bit will read ‘0’ and should not be written to a logic ‘1’.

Bit 0 - CS1_EM_DIS - Disables the Custom charger emulation profile.



‘0’ - The Custom charger emulation profile is enabled.



‘1’ (default) - The Custom charger emulation profile is not enabled.

10.13.2

Custom Stimulus / Response Pair X - Config 1 - 41h, 45h, 49h

The contents of this register are retained in Sleep.

Bit 6 - CS1_SX_TD_TYPE - Determines the behavior of the stimulus timer.



‘0’ - The stimulus timer is a delay from when the stimulus is detected until the response is

performed.



‘1’ - The stimulus timer controls how long the response is applied after the stimulus is detected.

The response is applied immediately and held for the duration of the timer then removed (if the

stimulus has been removed).

Bits 5 - 3 - CS1_SX_TD[2:0] - Determines the stimulus X tSTIM_DEL value as shown in Table 10.27.

Bits 2 - 0 - CS1_STIMX[2:0] - Determines the stimulus that is used as shown in Table 10.28.

10.13.3

Custom Stimulus / Response Pair X - Config 2 - 42h, 46h, 4Ah

The contents of this register are retained in Sleep.

Bits 7 - 4 - CS1_SX_RXMAG[3:0] - Determines the magnitude of the response to the stimulus. The bit

decode changes meaning based on which response was selected as shown in Table 10.30.

Table 10.31 through Table 10.33 show the specific decode for each function.

Bits 3 - 0 - CS1_SX_RX[3:0] - Defines the stimulus response as shown in Table 10.29.

10.13.4

Custom Stimulus / Response Pair X - Config 3 - 43h, 47h, 4Bh

The contents of this register are retained in Sleep.

Bits 5 - 4 - CS1_SX_PUPD[1:0] - Determines the magnitude of the pull-down current applied on the

DPOUT and DMOUT pins when the stimulus response is to apply a voltage and the voltage magnitude

is set at pull-down (0000b). The bit decode is given in Table 10.34.

Bits 3 - 0 - CS1_SX_TH[3:0] - Defines the threshold value, as shown in Table 10.35, for the specified

stimulus. If the stimulus is VBUS is ready to be applied or applied (i.e., CS1_STIMX[2:0] = 000b or

111b), the threshold value is ignored.
