23.3.50 CAM Entry Table POST1 Register (TSU_POST1)
When using the CAM, the conditions for referring to each CAM entry table can be specified by
using the TSU_POST1 to TSU_POST4 registers. TSU_POST1 specifies the conditions for
referring to TSU_ADRH0 to TSU_ADRH7 and TSU_ADRL0 to TSU_ADRL7. The settings of
this register are valid when the POSTENU bit in TSU_FWSLC is set to 1.
