The PFC_MASK value for the PFC_mx register was previously hardcoded as `0x07`, which is correct for SoCs in the RZ/G2L family but insufficient for RZ/V2H and RZ/G3E, where the mask value should be `0x0f`. This discrepancy caused incorrect PFC register configurations on RZ/V2H and RZ/G3E SoCs.
On the RZ/G2L, the PFC_mx bitfields are also 4 bits wide, with bit 4 marked as reserved. The reserved bits are documented to read as zero and be ignored when written. Updating the PFC_MASK definition from `0x07` to `0x0f` ensures compatibility with both SoC families while maintaining correct behavior on RZ/G2L.
