MB90390 Series
57
Bit setting : ESCR2/3 : SCES
= 1, ECCR2/3 : SCDE = 0
(TA
= 40 °C to +85 °C, VCC = 3.5 V to 5.5 V, VSS = 0 V)
Notes :
CL is load capacity value of pins when testing.
Depending on the used machine clock frequency, the maximum possible baud rate can be limited by
some parameters. These parameters are shown in “MB90390 series hardware manual”.
tCP is the machine clock cycle time. Refer to “ (1) Clock timing”.
