7.4 Radar Control Subsystem

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 receiving high-speed sensor data samples such as samples.

Within the device pin list 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.

Table 7-1 Radar Front-End (FE) Control Signals
Signal Name Description and Intended Function
FE1_REFCLK Radar front-end reference clock detection input. Can 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. Can drive the attached radar front-end frame trigger, or detect the frame trigger source.
HW_SYNC_FE2
NERRORIN_FE1 Radar front-end error status input. Can detect error output status of attached radar front-end.
NERRORIN_FE2
NRESET_FE1 Radar front-end reset output. Can drive reset of attached radar front-end.
NRESET_FE2
NWARMRESET_IN_FE1 Radar front-end warm reset input/output. Can drive warm reset of attached radar front-end, or detect reset status.
NWARMRESET_IN_FE2
