Register Description by Block
32-bit values
24-bit values
16-bit values
_0
LSB _L or _0
LSB _L
LSB
_1
_M or _1 MSB _U
USB
_2
_U or _2 USB
_3
USB
Note:
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:
[41:40] [39:32]
[31:24]
[23:16]
[15:8]
[7:0]
01
F4
F3
F2
F1
F0
A read from address 9000 will return F0; a read from address 9001 will return F1, etc.
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:
[47:40]
[39:32]
[31:24]
[23:16]
[15:8]
[7:0]
F0
F1
F2
F3
F4
F5
A read from address E300 will return F0, a read from address E301 will return F1, and so on.
