Will an ESP32-S3_WROOM-1 do 3 wire half duplex SPI ?

This table (https://docs.espressif.com/projects/esp ... tocol.html) says that an ESP32-S3 v2 will do the SPI Slave Half Duplex protocol. Does that mean that v1 will not ?

How does one tell if a processor is v1 or v2 ?

When did the changeover from v1 to v2 happen ?

Thanks

Update: ESP32-S3-WROOM-1 and -2 have exactly the same SPI wording in their respective datasheets. No mention is made of V2 having extra capabilities over V1.
