23.3.53 CAM Entry Table POST4 Register (TSU_POST4)
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_POST4 specifies the conditions for
referring to TSU_ADRH24 to TSU_ADRH31 and TSU_ADRL24 to TSU_ADRL31. The settings
of this register are valid when the POSTENL bit in TSU_FWSLC is set to 1.
