Figure 20.10
(1) UFORM Bit in U2C0 Register = 0 (LSB first)
(2) UFORM Bit in U2C0 Register = 1 (MSB first)
The above diagram applies under the following conditions:
• CKPOL bit in U2C0 register = 0 (transmit data is output at the falling edge and
• U2LCH bit in U2C1 register = 0 (not inverted)
• STPS bit in U2MR register = 0 (one stop bit)
• PRYE bit in U2MR register = 1 (parity enabled)

receive data is input at the rising edge of the transfer clock)
As shown in Figure 20.10, the transfer format is selected with the UFORM bit in the U2C0 register. This
function is enabled when transfer data is 8 bits long. Figure 20.10 shows the Transfer Format.
