Operation
2.5.5 Operation of Serial I/O (reception used for SIM interface)
In receiving data in UART mode (used for SIM interface), choose functions from those listed in Table
2.5.7. Operations of the circled items are described below. Figure 2.5.17 shows the operation timing, and
Figures 2.5.18 and 2.5.19 show the set-up procedures.

(1) Setting the transmit enable bit and receive enable bit to “1” readies data-receivable status.
(2) When the first bit (the start bit) of reception data is received from the RxD
(3) When the stop bit(s) is (are) received, the content of the UART2 receive register is transmit-
