Cautions 1. Connect the REGC pin to VSS via a capacitor (0.47 to 1 μ F: recommended).
2. Only the bottom side pins (pin numbers 23 and 24) correspond to the UART6 pins (RxD6 and
TxD6) when writing by a flash memory programmer. Writing cannot be performed by the top
side pins (pin numbers 48 and 47).
3. Make V
DD (pin number 14) and VDD (pin number 35), VSS (pin number 13) and VSS (pin number
36) the same potential.
Remark The functions within arrowheads (< >) can be assigned by setting the input switch control register (ISC).
