The MCU seems to most closely resemble an NEC (Renesas) 78K0R/Kx3-L 64-pin FBGA: https://www.renesas.com/us/en/document/mah/78k0rkx3-l-users-manual-hardware-r01uh0106ej040078k0rkx3l?language=en&r=1051991
 +
 +
The functional pin mapping is almost exactly the same, except the GPIO port assignment is almost completely different.
 +
 +
Most low port numbers appear to map to the correct physical pin locations as described in the above datasheet, however around P7 and above this mapping is definitely altered.
