Chapter 13 UART
13.4 Specifying port registers
13.4.1 Functioning P43(TXD0) and P42(RXD0) as the UART
and Chapter 18, “Port 0” for detail about the port registers.
the value "1" selects the P43.
To enable the UART function, the applicable bit of each related port register needs to be set. See Chapter 21, “Port 4”
Set P43MD1-P42MD1 bits(bit3-bit2 of P4MOD1 register) to “0” and set P43MD0-P42MD0(bit3-bit2 of P4MOD0
register) to “1”, for specifying the UART as the secondary function of P43 and P42.
Set the P43C1 bit (P4CON1 register's bit 3) to "1", the P43C0 bit (P4CON0 register's bit 3) to "1", and the P43DIR bit
(P4DIR register's bit 3) to "0" for specifying the state mode of the P43 pin to CMOS output.
Set P42DIR bit (bit2 of P4DIR register) to “1” for specifying the P42 as an input pin.
The set value ($) is arbitrary for the P42C1 and P42C0 bits. Select an arbitrary input mode depending on the state of the
external circuit to which the P42 pin is connected.
The P43D to D42D bits (P4D register bits 3 to 2) data can either be "0" or "1" (not need to be set).
* : Bit not related to the UART function
** : Don’t care
[Note:]
The receive pin (RXD) is selected by U0RSEL bit (bit4 of UA0MOD0 register). The initial value "0" selects the P02 and
