// i_setup[29:28] Indicates the number of data bits per word. This will
// either be 2'b00 for an 8-bit word, 2'b01 for a 7-bit word, 2'b10
// for a six bit word, or 2'b11 for a five bit word.
//
// i_setup[27] Indicates whether or not to use one or two stop bits.
// Set this to one to expect two stop bits, zero for one.
//
// i_setup[26] Indicates whether or not a parity bit exists. Set this
// to 1'b1 to include parity.
//
// i_setup[25] Indicates whether or not the parity bit is fixed. Set
// to 1'b1 to include a fixed bit of parity, 1'b0 to allow the
// parity to be set based upon data. (Both assume the parity
// enable value is set.)
//
// i_setup[24] This bit is ignored if parity is not used. Otherwise,
// in the case of a fixed parity bit, this bit indicates whether
// mark (1'b1) or space (1'b0) parity is used. Likewise if the
// parity is not fixed, a 1'b1 selects even parity, and 1'b0
// selects odd.
//
// i_setup[23:0] Indicates the speed of the UART in terms of clocks.
// So, for example, if you have a 200 MHz clock and wish to
// run your UART at 9600 baud, you would take 200 MHz and divide
// by 9600 to set this value to 24'd20834. Likewise if you wished
