UART mode connection diagram (during communication at different potential)

UART mode bit width (during communication at different potential) (reference)

Remark 1.

Rb[

Ω]: Communication line (TxDq) pull-up resistance,

Cb[F]: Communication line (TxDq) load capacitance, Vb[V]: Communication line voltage

Remark 2.

q: UART number (q = 0 to 3), g: PIM and POM number (g = 0, 1, 5, 14)

Remark 3.

fMCK: Serial array unit operation clock frequency

(Operation clock to be set by the CKSmn bit of serial mode register mn (SMRmn).

m: Unit number, n: Channel number (mn = 00 to 03, 10 to 13))

Remark 4.

UART2 cannot communicate at different potential when bit 1 (PIOR01) of peripheral I/O redirection register 0 (PIOR0) is
