register) to “1”, for specifying the UART as the secondary function of P43 and P42.
bit(bit3 of P4DIR register) to “0”, for specifying the P43 as CMOS output.
function.
When you want to make sure the UART function is working, please check related port registers are specified. See
Set P43MD1-P42MD1 bits(bit3-bit2 of P4MOD1 register) to “0” and set P43MD0-P42MD0(bit3-bit2 of P4MOD0
Set P43C1 bit(bit3 of P4CON1 register) to “1”, set P43C0 bit(bit3 of P4CON0 register) to “1”, and set P43DIR
Set P42DIR bit(bit2 of P4DIR register) to “1” for specifying the P42 as an input pin.
Data setting to P42C1 bit and P42C0 bit, depend on the application circuit connected to P42.
Data of P43D-P42D bits (bit3-2 of P4D register) do not affect to the UART function, so don’t care the data for the
