94 / 114 page  UCS1002-3 DS20006852A-page 94 2023 Microchip Technology Inc. and its subsidiaries bit 3-0 CS_S3_R3[3:0]: Defines the stimulus response as shown below. 0000 = Remove previous response on DPOUT and DMOUT 0001 = Apply voltage on DPOUT (Note 1). 0010 = Apply voltage on DMOUT (Note 2). 0011 = Apply voltage on DPOUT and DMOUT. 0100 = Connect resistor from DPOUT to GND (Note 1). 0101 = Do not use. 0110 = Connect voltage divider from VBUS to GND with the center tap at DPOUT (Note 1). 0111 = Connect resistor form DMOUT to GND (Note 2). 1000 = Do not use. 1001 = Connect voltage divider from VBUS to GND with the center tap at DMOUT (Note 2). 1010 = Connect 200resistor from DPOUT to DMOUT. 1011 = Do not use. 1100 = Connect voltage divider from VBUS to GND with the center tap at DPOUT and DMOUT. 1101 = Connect resistor from DPOUT to GND and DMOUT to GND. 1110 = If CS_STIM3 = 000, the 15 kpull-down resistors applied to DPOUT and DMOUT during Emulation Reset are not removed. If CS_STIM3 = 111, the 15 kpull-down resistors applied to DPOUT and DMOUT during Emulation Reset are removed. For all other CS_STIM3 settings, whatever is applied is not changed. 1111 = Same as 1110 case above. Note 1: If CS_STIM3[2:0] = 000b and no other response is applied to the DPOUT pin, the 15 k pull-down resistor applied to the DPOUT pin during Emulation Reset is not removed. Otherwise, the previous response is left on the DPOUT pin (if applicable) or the 15 k pull-down resistor is removed. 2: If CS_STIM3[2:0] = 000b and no other response is applied to the DMOUT pin, the 15 k pull-down resistor applied to the DMOUT pin during Emulation Reset is not removed. Otherwise, the previous response is left on the DMOUT pin (if applicable) or the 15 k pull-down resistor is removed. REGISTER 10-46: CUSTOM EMULATION STIMULUS 3 CONFIGURATION 3 REGISTER (ADDRESS 4Bh) U-x U-x R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 — — CS_S3_PUPD[1:0] CS_S3_TH[3:0] bit 7 bit 0 Legend: R = Readable bit W = Writable bit U = Unimplemented bit -n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown bit 7-6 Unimplemented bit 5-4 CS_S3_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 as follows. 00 = 10 µA 01 = 50 µA 10 = 100 µA 11 = 150 µA REGISTER 10-45: CUSTOM EMULATION STIMULUS 3 CONFIGURATION 2 REGISTER (ADDRESS 4Ah) (CONTINUED) |
