PRODUCTION DATA
The radar control subsystem (RCSS) integrates a high-bandwidth interconnect with a pair of 4-lane, CSI 2.0 receivers (CSI2_RX0 and CSI2_RX1), two SPI controllers (RCSS_SPIA and RCSS_SPIB), I2C controllers and a set of GPIO. The SPI, I2C and GPIO peripherals can be utilized for controlling and configuring the attached sensor devices. The CSI 2.0 receivers allow for receiveing high-speed sensor data samples such as samples.
Within the device pinlist there are also a number of pins which have been named in support of a radar front-end connection use-case. All of these signals resolve to various MSS/RCSS GPIO functionality in the device pinmux and therefore do not exist in the list of pinmux signal. See the below description of these signals.
Signal Name | Description and Intended Function |
---|---|
FE1_REFCLK | Radar front-end refrence clock detection input. Could be attached to output clock available from radar front-end device. |
FE2_REFCLK | |
HW_SYNC_FE1 | Radar front-end frame synchronization output trigger input/output. Could be used to drive the attached radar front-end frame trigger, or used to detect the frame trigger source. |
HW_SYNC_FE2 | |
NERRORIN_FE1 | Radar front-end error status input. Could be used to deted error output status of attached radar front-end. |
NERRORIN_FE2 | |
NRESET_FE1 | Radar front-end reset output. Could be used to drive reset of attached radar front-end. |
NRESET_FE2 | |
NWARMRESET_IN_FE1 | Radar front-end warm reset input/output. Could be used to drive warm reset of attached radar front-end, or detect reset status. |
NWARMRESET_IN_FE2 |
