Branch over following JSR instruction
|
|
A branch with argument $03 skips the following 3 bytes.
|
|
A JSR instruction has the initial byte value of $20.
|
|
Therefore $F0 $XX $20 is part of a
|
|
Bxx +
|
|
JSR $xxxx

instruction sequence.
|
|
This is a very common construction, and the logical way to
|
|
