24.2
PFC has the following registers. For details on register addresses and register states in each
operation mode, refer to section 27, List of Registers.
• Port A control register (PACR)
• Port B control register (PBCR)
• Port D control register (PDCR)
• Port E control register (PECR)
• Port G control register (PGCR)
• Port H control register (PHCR)
• Pin select register A (PSELA)
• I/O buffer Hi-Z control register A (HIZCRA)
• Noise canceller control register (NCCR)
Note: The PFC registers are not initialized by a manual reset and hold the contents.
24.2.1
