MASKSet pointed pins to 0 or 1. You can also invert pointed pins or stay they untouched.
Syntax[mask] [+|-|~|&|?] <mask> [count] [mask] <extmask> [count] [+|-|~|&] <mask> [count] <extmask> [count] Parameters<mask>
<extmask>
RemarksIt is necessary to specify new state for all 12 output pins (or less in case using cmd count) then you use 1-st mask syntax (like 111000). All unspecified bits will be filled by same state like last specified byte. For example:1010 is equivalent to 101000000000 0101 is equivalent to 010111111111 1 is equivalent to 111111111111 0 is equivalent to 000000000000 11110 is equivalent to 111100000000 Examples// Syntax 1
1 ; Set all outputs to HIGH state
!00000000000 ; Invert first output state and resEt the rest outputs
!xxxxxxxxxxx ; Invert first output state and stay untouched the rest outputs
011111111111 ; Reset first output state and set reset outputs to HIGH state
// Syntax 2
mask +(1,2) ; Set 1 and 2 outputs to HIGH state (rest stay untouched)
+(7) ; Set output no. 7 to HIGH state (rest stay untouched)
-(1,3,5) ; Set 1, 3 and 5 outputs to LOW state (rest stay untouched)
~(4,6) ; Invert 4 and 6 outputs (rest stay untouched)
&(7,8) ; Say untouched state of 7 and 8 outputs (and resEt the rest outputs)
?(9,10) ; Randomize state of 9 and 10 outputs
