1.7 Precautions for Serial I/O (UART Mode)

1.7.1 Special Mode 2

If a low-level signal is applied to the P8
phase output forcible cutoff by input on SD pin enabled), the RTS
state.

1.7.2 Special Mode 4 (SIM Mode)

A transmit interrupt request is generated by setting the U2C1 register U2IRS bit to "1" (transmission
complete) and U2ERE bit to "1" (error signal output) after reset. Therefore, when using SIM mode, be
sure to clear the IR bit to "0" (no interrupt request) after setting these bits.
