In this mode, data of 1 byte is transmitted/received following a start bit, and a full-duplex operation can be
A dedicated UART baud rate generator is incorporated, so that communication can be executed at a wide range of
<1> Set the CKSR6 register (see Figure 14-8).
<2> Set the BRGC6 register (see Figure 14-9).
<3> Set bits 0 to 4 (ISRM6, SL6, CL6, PS60, PS61) of the ASIM6 register (see Figure 14-5).
<4> Set bits 0 and 1 (TXDLV6, DIR6) of the ASICL6 register (see Figure 14-10).
<5> Set bit 7 (POWER6) of the ASIM6 register to 1.
<6> Set bit 6 (TXE6) of the ASIM6 register to 1.
<7> Write data to transmit buffer register 6 (TXB6).
The basic procedure of setting an operation in the UART mode is as follows.
