15.1.1.4 Continuous Receive Mode
15.1.1.3 LSB First/MSB First Select Function
In continuous receive mode, receive operation becomes enable when the receive buffer register is read.
It is not necessary to write dummy data into the transmit buffer register to enable receive operation in
this mode. However, a dummy read of the receive buffer register is required when starting the operating
mode.
When the UiRRM bit (i = 0 to 2) = 1 (continuous receive mode), the TI bit in the UiC1 register is set to 0
(data present in UiTB register) by reading the UiRB register. In this case, i.e., UiRRM bit = 1, do not write
dummy data to the UiTB register in a program. Bits U0RRM and U1RRM are bits 2 and 3 in the UCON
register, respectively, and the U2RRM bit is the bit 5 in the U2C1 register.
Use the UFORM bit in the UiC0 register (i = 0 to 2) to select the transfer format.
Figure 15.13 shows the Transfer Format.

(1) When the UFORM bit in the UiC0 register = 0 (LSB first)
(2) When the UFORM bit = 1 (MSB first)
i = 0 to 2
* This applies to the case where the CKPOL bit in the UiC0 register = 0
