LPC2103 Registers Help!

Hi guys. I have a problem here. I'm new to LPC2103, previously been using 8051. I will explain in 8051 register instead of LPC2103 and hope you can enlighten me.

In 8051, there is SBUF, RI and TI bits. I would like to know which registers does similar functions respectively in LPC2103.

Your help is greatly appreciated. Thanks!

  • Hi there. Thanks for the reply. I have seen the data sheet and user manual. but i am still unable to differentiate which registers acts like SBUF, RI and TI. In my opinion, i think that U0THR acts like a SBUF, RDR(bit0 of U0LSR) acts like a RI bit and THRE(bit5 of U0LSR) acts like a TI bit. Hope you can enlighten me further. Thanks!
