The R5FSS has two physical and three logical low latency peripheral ports:
The CPU requires the Virtual Peripheral Port to be mapped to a subset of (or complete) range of the Normal Peripheral Port. The Virtual Peripheral Port is disabled by default, and must be enabled by a System Control Coprocessor register write.
On this Device, the Virtual Peripheral Port is mapped to the same base address and size of the normal peripheral port. Although possible, the user should not enable the virtual peripheral port because the virtual port supports fewer (3 versus 15) outstanding writes, and enabling it will impact performance.
Interrupt outputs: FPIXCm, FPUFCm, FPOFCm, FPDZCm, FPIDCm, and FPIOCm from R5F are not connected. Consequently, the only way to check the status of the cumulative exception status flags is by reading the FPSCR register.
