the SENI signal of the first device in a chain must be held LOW. The SENO signal
of a device should connect to the SENI of the next device in the chain. The SENO
of the final device is used to indicate that the programming of all devices is
complete. When the master device (ID=’000') SENO signal goes LOW the
internal programming is complete and queue write/read operation may begin.
Please refer to Figure 39, Parallel Programming for signal timing details.

operating mode during the master reset cycle (i.e. on the rising edge of Master
Reset (MRS)). The second stage is to set values such as PAE/PAF, number
of queues, queue depth, etc. using the programming mode (serial, parallel,
default) selected in stage 1. Refer to Figure 4, Device Programming Hierarchy.
Configuring the device is a 2 stage sequence. The first stage is to set the
