Description

read_param

Input

No Read signal for the parameter specified in

param[] input port and fed to data_out[]

output port.

Signal indicating the parameter specified on the

param[] port should be read. The number of bits

set on data_out[] depends on the parameter

type. The signal is sampled at the rising clock

edge. Assert the signal for only one clock cycle to

prevent the parameter from being read again in a

subsequent clock cycle.

The busy signal is activated as soon as read_

param is read as active. While the parameter is

being read, the busy signal remains asserted, and

data_out[] has invalid data. When the busy

signal is deactivated, data_out[] is valid,

another parameter can be read.
