Subject: [oc] uart modem outputs
Hi. I was looking at the UART16550 core and want to clarify
something. On the pdf document (UART Core Specification), it is
indicated on section 4.6 Modem Control Register that the value of RTS
and DTR (these are RTS_PAD_O and DTR_PAD_O right?) are the complement of
what is set on the MCR. But in uart_regs.v, I found these assignments
assign rts_pad_o = mcr[`UART_MC_RTS];
assign dtr_pad_o = mcr[`UART_MC_DTR];
I didn't found anywhere in the code a statement that will assign the
complement of the MCR value to RTS/DTR. Which is correct? The document
or the code? Please clarify.
Thank you very much.
Leo
