27 / 32 page  FUSB302B www.onsemi.com 27 Table 37. STATUS0 (Address: 40h; Reset Value: 0x0000_0000; Type: Read) Bit # Name R/W/C Size (Bits) Description 7 VBUSOK R 1 1: Interrupt occurs when VBUS transitions through vVBUSthr. This bit typically is used to recognize port partner during startup 6 ACTIVITY R 1 1: Transitions are detected on the active CC* line. This bit goes high after a minimum of 3 CC transitions, and goes low with no Transitions 0: Inactive 5 COMP R 1 1: Measured CC* input is higher than reference level driven from the MDAC 0: Measured CC* input is lower than reference level driven from the MDAC 4 CRC_CHK R 1 1: Indicates the last received packet had the correct CRC. This bit remains set until the SOP of the next packet 0: Packet received for an enabled SOP* and CRC for the enabled packet received was incorrect 3 ALERT R 1 1: Alert software an error condition has occurred. An alert is caused by: TX_FULL: the transmit FIFO is full RX_FULL: the receive FIFO is full See Status1 bits 2 WAKE R 1 1: Voltage on CC indicated a device attempting to attach 0: WAKE either not enabled (WAKE_EN=0) or no device attached 1:0 BC_LVL[1:0] R 2 Current voltage status of the measured CC pin interpreted as host current levels as follows: 00: < 200 mV 01: > 200 mV, < 660 mV 10: > 660 mV, < 1.23 V 11: > 1.23 V Note the software must measure these at an appropriate time, while there is no signaling activity on the selected CC line. BC_LVL is only defined when Measure block is on which is when register bits PWR[2]=1 and either MEAS_CC1=1 or MEAS_CC2=1 Table 38. STATUS1 (Address: 41h; Reset Value: 0x0010_1000; Type: Read) Bit # Name R/W/C Size (Bits) Description 7 RXSOP2 R 1 1: Indicates the last packet placed in the RxFIFO is type SOP” (SOP double prime) 6 RXSOP1 R 1 1: Indicates the last packet placed in the RxFIFO is type SOP’ (SOP prime) 5 RX_EMPTY R 1 1: The receive FIFO is empty 4 RX_FULL R 1 1: The receive FIFO is full 3 TX_EMPTY R 1 1: The transmit FIFO is empty 2 TX_FULL R 1 1: The transmit FIFO is full 1 OVRTEMP R 1 1: Temperature of the device is too high 0 OCP R 1 1: Indicates an over-current or short condition has occurred on the VCONN switch |
