The column base / circular buffer stuff:
0000 0000 0000 0110 cbclr Clear vector column base ie SR[5:4]
= 0
0000 0000 0000 0111 cbinc Increment vector column base ie
SR[5:4]++
0000 0000 0000 1000 cbchg Toggle vector column base ie SR[5] =
~SR[5]
0000 0000 0000 1001 cbdec Decrement vector column base ie
SR[5:4]--Is:
cbclr, cbadd1, cbadd2
Syntax:
R(y,CB+x) becomes R(y,x)*
eg.
vadd HX(14++,0)*, HX(14++,0)*, HX(63,32) REP 2
cbadd2
