(1) UFORM Bit in U2C0 Register = 0 (LSB first)
(2) UFORM Bit in U2C0 Register = 1 (MSB first)
The above applies under the following conditions:
If a communication error occurs while transmitting or receiving in UART mode, follow the procedures below:
• Resetting the U2RB register
(1) Set the RE bit in the U2C1 register to 0 (reception disabled).
(2) Set the RE bit in the U2C1 register to 1 (reception enabled).
• Resetting the U2TB register
(1) Set bits SMD2 to SMD0 in the U2MR register to 000b (serial interface disabled).
(2) Reset bits SMD2 to SMD0 in the U2MR register to 100b, 101b, and 110b.
(3) Write 1 to the TE bit in the U2C1 register (transmission enabled), regardless of the TE bit value of the
As shown in Figure 24.9, the UFORM bit in the U2C0 register can be used to select the transfer format. This
function is enabled when transfer data is 8 bits long. Figure 24.9 shows the Transfer Format.
