|

| 11 | | Displays the event at 'ep', scrolling in direction 'sd', by
|
---|
| 12 | | updating 'gdstb'. Uses the accidental code in 'ac_code', and
|
---|
| 13 | | the note type table 'nsvtab'. Checks 'cf' to determine if
|
---|
| 14 | | we're displaying in the center of the screen.
|
---|
| 15 | | Allocates gdsel events as needed for new events.

| 126 | | A few words about se_disp:
|
---|
| 127 | | --------------------------
|
---|
| 128 | | se_disp has to be very fast, so it's written in assembly language,
|
---|
| 129 | | rather than C, which is usually pretty good, but not quite good enough
|
---|
| 130 | | for this application. The faster this routine runs, the higher the
|
---|
| 131 | | tempo we can keep up with. If this code is fast enough, we end up
|
---|
| 132 | | hardware limited by the maximum rate of the timer, and the VSDD update rate.
|
---|
| 133 |
|
---|
| 134 | _se_disp: link a6,#0 | allocate and link stack frame
|
---|
| 135 | movea.l P_EP(a6),a0 | get event pointer 'ep' into a0
|
---|
| 136 | move.b E_TYPE(a0),d1 | get event type into d1.W
|
---|
| 137 | andi.w #0x007F,d1 | mask off new-note flag
|
---|
| 138 | cmp.b #N_ETYPES,d1 | see if it's valid

---|

---|

|
---|

|
---|

|
---|
| 147 | jmp (a2) | jump to event display routine
|
---|
| 148 |
|
---|
| 149 | | On entry, the individual display routines only depend on a0 pointing at the
|
---|
| 150 | | event they were dispatched for. Registers a6 and a7 have their usual meaning,
|
---|
| 151 | | a6 = frame pointer, a7 = stack pointer.
|
---|
| 152 |
|
---|
| 153 | | d0..d2 are used for scratch, as are a0..a2, and are not saved by this code.
