ADE3800

They are all LSB aligned, except for OMUX which is MSB aligned.

When the RAM width is not a multiple of 8, zeros will be returned for the non-meaningful bits.

Example of LSB aligned RAM

If addresses 9000-9005 are written with the values F0-F5, the contents of SCL_RAM_1 (at word

address 0) are as follows:

A read from address 9000 will return F0; a read from address 9001 will return F1, etc.

Note:

A read from 9005 returns the value 01 (as opposed to F5) since there are only 2 meaningful bits of

data at this address.

Example of MSB aligned RAM (OMUX only)

If addresses E300-E305 are written with the values F0-F5 respectively, the contents of the OMUX

RAM (at word address 0) are as follows:

A read from address E300 will return F0, a read from address E301 will return F1, and so on.
