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.
