8051 and a C switch statement

Got a 4k8 serial biphase signal being decoded by a at85c52 with an
external non retrig monostable (hc221), and I'm running out of time
occasionally waiting for the generic 2*8 LCD to clear it's busy flag.
The LCD is fed with the info from the incoming biphase
To reduce the "reaction time" I could use a long switch statement on
the signal's clock interrupt bitcount from the sync word, 80 per
frame, do just a little bit each interrupt.
The real question is
" how big can I make the switch statement?"
Whats the limit?
I'm using the rasionance C compiler.
'scuse typos, a bottle of wine was preferable to staring at my
lamentable code
