40 / 65 page  Table 9-13. GPIO1_CONFIG Register Field Descriptions (continued) Bit Field Type Reset Description 3-0 GPIO1_OUTPUT_SELEC T R/W 0h GPIO1 Output Selection 0h = Remote Wakeup - host repeater is receiving remote wake but has not seen start of resume 1h = USB disconnect - host repeater is actively forwarding LS/FS disconnect. 2h = USB_HS_Unsquelched - host repeater in L0 seeing USB HS or in reset seeing Chirp 3h = PVTB - HOST repeater is actively transmitting ESE1 due to HS disconnect. 4h = DEFAULT - waiting to be configured host/peripheral 5h = HOST - in host repeater mode 6h = PERIPHERAL - in peripheral repeater mode 7h = CONNECTED - repeater is connected, connection seen acknowledged by start of reset 8h = RESET - reset in progress, reset is detected is high, L0 is low 9h = L0 - fully configured and repeating data, keep-alive and reset/ disconnect Ah = L1 -device has received CM.FS/CM.L1,has stopped repeating and is waiting for wake/resume Bh = L2 - device has received CM.L2, has stopped repeating and is waiting for wake/resume. Ch = GPIO1_HS_TEST - in host repeater in L0 mode, received CM.TEST Dh = HIGH_OUTPUT - output is forced static high Eh = LOW_OUTPUT - output is forced static low Fh = OVP - over voltage (DP/DN voltage > VOVP_TH) detected on the USB DP/DN 9.1.12 LOPWR_N_UART_P1 Register (Offset = 50h) [Reset = 50h] LOPWR_N_UART_P1 is shown in Table 9-14. Return to the Summary Table. Table 9-14. LOPWR_N_UART_P1 Register Field Descriptions Bit Field Type Reset Default from OTP (Y/N) Description 7 RESERVED R 0h 6 HOST_FRAME_LP_EN _P1 RH/W 1h Y Host repeater frame-based Low Power enable Default through OTP 0h = Not Enabled 1h = Enabled 5 DEVICE_FRAME_LP_E N_P1 RH/W 0h Y Peripheral repeater frame-based Low Power enable Default through OTP 0h = Not Enabled 1h = Enabled 4 IDLE_LP_EN_P1 RH/W 1h Y enable response-based Low Power mode Default through OTP 0h = Not Enabled 1h = Enabled 3 UART_GPI_POLARITY _P1 RH/W 0h Y Select polarity of pin to enable UART mode Default through OTP 0h = GPIO1 pin enables UART mode when 1 1h = GPIO1 pin enables UART mode when 0 2 UART_DP_PU_EN_P1 RH/W 0h Y Select whether DP pullup is enabled during UART mode Default through OTP 0h = disable DP pullup during UART mode 1h = enable DP pullup during UART mode TUSB2E221 SNLS757B – JUNE 2024 – REVISED NOVEMBER 2024 www.ti.com 40 Submit Document Feedback Copyright © 2024 Texas Instruments Incorporated Product Folder Links: TUSB2E221 |
