12.2.1.7
PSRAM Burst Wrap BCR Bit
The burst wrap control bit defines whether there is a wrap around within a burst access
or not. In case of fixed 8-word burst length, this means that after word #7, word #0 is
going to be output in wrap mode.
In case of continuous burst mode the internal address counter will increment
continuously until terminated by the system. For continuous burst mode or non-wrap
mode, the burst access must be terminated prior to a row boundary crossing.
The burst wrap setting is used for both Write and Read operations.
12.2.1.8
PSRAM Burst Length BCR Bit
The burst length setting defines the Wrap boundary whenever Burst Wrap is enabled by
setting BCR3 = 0b. When Burst Wrap is disabled by setting BCR3 = 1b, all burst behave
as Continuous Bursts regardless of the Burst Length setting. Furthermore all fixed
length bursts (4-, 8-, 16-, and 32-word bursts) will continue until terminated by
bringing CE# high or interrupted by initiating a new burst access. Continuous Burst and
Fixed Length Burst with Wrap Off will increment the address until a row boundary
crossing is reached. Fixed Length Bursts will continue to wrap around and cycle through
their limited address space until terminated or interrupted. The burst length setting is
used for both Write and Read operations.
