COMMANDS FOR MICROCHIP (USES SPEED AND POLARITY WITH K0-K1 SET IN MODE 0)

S=START BIT PROCESSING
T=TIMEOUT IN STRING
G0-G1=VDD (MOSI) PIN DOWN-UP CONTROL (WEAK) bit0=PB3=MOSI
G0-G2=LVP (MISO) PIN DOWN-UP CONTROL (OPEN DRAIN IMITATION)(=NEW) bit1=PB4=MISO
G0-G4=MCLR (SCK) PIN DOWN-UP CONTROL (WEAK) bit2=PB5=SCK
(OLD FIRMWARE MUST SKIP NEW COMMANDS)
***X0-X1 not used??? -USED!!! DIRECT SDA-SCL CONTROL! USE SPEED!!! (and speed-assisted pause between bytes!)
X0-X1=SDA tik-setsda
X0-X2=SCL tik-setscl


for K0 tik-dataset-sclup-tik-latchdata-scldown
for K1 dataset-tik-sclup-latchdata-tik-scldown

pic32 sample on falling pulse, but set data on falling pulse
dspic30f - all sample on falling, set on rise
pic 24 sample in by rise, et data by rise!
pic18, pic84 tx on rise, sample by fall, read too


mclr enable 13v by hi-level or low level
mclr driven by sck-pin from header (weak levels)
vdd driven by mosi-pin from header (weak levels)
default levels for idle = low (with K0 in mode 0)= HI IMPEDANCE ON START MODE!
