4 / 13...20
REP {#}D,{#}S
Execute next D[8:0] instructions S times. If S = 0, repeat instructions infinitely. If D[8:0] = 0, nothing repeats.

RETI1
Return from INT1. (CALLD $1FF,$1F5 WCZ)
4 / 13...20
RETI2
Return from INT2. (CALLD $1FF,$1F3 WCZ)
4 / 13...20
RETI3
Return from INT3. (CALLD $1FF,$1F1 WCZ)
4 / 13...20
SKIP {#}D
Skip instructions per D. Subsequent instructions 0..31 get cancelled for each '1' bit in D[0]..D[31].
2 / 2
SKIPF {#}D
Skip cog/LUT instructions fast per D. Like SKIP, but instead of cancelling instructions, the PC leaps over them.
2 / ILLEGAL
TJF D,{#}S
Test D and jump to S** if D is full (D = $FFFF_FFFF).
2 or 4 / 2 or 13...20
TJNF D,{#}S
Test D and jump to S** if D is not full (D != $FFFF_FFFF).
2 or 4 / 2 or 13...20
TJNS D,{#}S
Test D and jump to S** if D is not signed (D[31] = 0).
2 or 4 / 2 or 13...20
TJNZ D,{#}S
Test D and jump to S** if D is not zero.
2 or 4 / 2 or 13...20
TJS D,{#}S
Test D and jump to S** if D is signed (D[31] = 1).
2 or 4 / 2 or 13...20
TJV D,{#}S
Test D and jump to S** if D overflowed (D[31] != C, C = 'correct sign' from last addition/subtraction).
2 or 4 / 2 or 13...20
TJZ D,{#}S
Test D and jump to S** if D is zero.

Instruction
Description
Clocks
Cog & LUT / Hub
Hub Control
COGID {#}D {WC}
If D is register and no WC, get cog ID (0 to 15) into D. If WC, check status of cog D[3:0], C = 1 if on.
2...9, +2 if result / same
COGINIT {#}D,{#}S {WC}
Start cog selected by D. S[19:0] sets hub startup address and PTRB of cog. Prior SETQ sets PTRA of cog.
2...9, +2 if result / same
COGSTOP {#}D
Stop cog D[3:0].
2...9 / same
LOCKNEW D {WC}
Request a LOCK. D will be written with the LOCK number (0 to 15). C = 1 if no LOCK available.
4...11 / same
LOCKREL {#}D {WC}
Release LOCK D[3:0]. If D is a register and WC, get current/last cog id of LOCK owner into D and LOCK status
into C.
2...9, +2 if result / same
LOCKRET {#}D
Return LOCK D[3:0] for reallocation.
2...9 / same
LOCKTRY {#}D {WC}
Try to get LOCK D[3:0]. C = 1 if got LOCK. LOCKREL releases LOCK. LOCK is also released if owner cog stops or
restarts.
2...9, +2 if result / same
HUBSET {#}D
Set hub configuration to D.
2...9 / same
Hub FIFO
GETPTR D
Get current FIFO hub pointer into D.
2 / FIFO IN USE
FBLOCK {#}D,{#}S
Set next block for when block wraps. D[13:0] = block size in 64-byte units (0 = max), S[19:0] = block start
address.
2 / FIFO IN USE
RDFAST {#}D,{#}S
Begin new fast hub read via FIFO. D[31] = no wait, D[13:0] = block size in 64-byte units (0 = max), S[19:0] =
block start address.
2 or WRFAST finish +
10...17 / FIFO IN USE
WRFAST {#}D,{#}S
Begin new fast hub write via FIFO. D[31] = no wait, D[13:0] = block size in 64-byte units (0 = max), S[19:0] =
block start address.
2 or WRFAST finish + 3 /
FIFO IN USE
RFBYTE D {WC/WZ/WCZ}
Used after RDFAST. Read zero-extended byte from FIFO into D. C = MSB of byte. *
2 / FIFO IN USE
