16.10.1.1 NRD Waveform

The NRD signal is characterized by a setup time, a pulse length and a hold time:

1. NRD_SETUP: the NRD setup time is defined as the setup of the address before the NRD falling edge.
2. NRD_PULSE: the NRD pulse length is the time between the NRD falling edge and the NRD rising edge.
3. NRD_HOLD: the NRD hold time is defined as the hold time of the address after the NRD rising edge.
