2.4.4 Serial I/O Precautions (UART Mode)
Description
When the level of the CLKi and CTSi pins goes to “H” (Note 1), if the UiMR register is set to
any of the following, the UiERE bit in the UiC1 register is set to “1” (parity error signal output
enabled). When the PRYE bit in the UiMR register is set to “1” while the UiERE bit is “1”
(parity error signal output enabled), the TXDi pin outputs “L” level if a parity error occurs
while receiving data. To prevent this, set the UiERE bit after setting the UiMR register.
• Change the setting of bits SMD2 to SMD0 from “000
• Change the setting of bits SMD2 to SMD0 from “001
• Change the setting of bits SMD2 to SMD0 from “001
• Change the setting of bits SMD2 to SMD0 from “001
• Change the setting of bits SMD2 to SMD0 from “010
Note 1: If the pins are not used as CLKi or CTSi, these conditions apply when the pin level
