Remarks 1. R
b[Ω]:Communication line (TxDq) pull-up resistance,
C
b[F]: Communication line (TxDq) load capacitance, Vb[V]: Communication line voltage
2. q: UART number (q = 0 to 3), g: PIM and POM number (g = 0, 1, 8, 14)
3. f
MCK: 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))
4. UART2 cannot communicate at different potential when bit 1 (PIOR1) of peripheral I/O redirection
register (PIOR) is 1.
