SPI SCK PIN initial value

Hardware Arduino Due
1

I'm trying to set SCK PIN initial value as HIGH, but I failed.
My setup code is as below.

void setup() {

pinMode(SS, OUTPUT);
digitalWrite(SS, HIGH);

SPI.begin();

digitalWrite(SCK, HIGH);
SPI.setDataMode(SPI_MODE3);
SPI.setClockDivider(SPI_CLOCK_DIV4);
Serial.begin(9600);

After one byte sending, SCK pin is high when inactive.
I tried to use pull-up resistance for SCK PIN, but I got same result.
Is there any way to set high value as initial time?
Thank you.

SPI_MODE3 does that

I don't understand what you mean.
SCK in SPI_MODE3 should be high when inactive.
But, when I set to MODE3. SCK pin is LOW at first time.
Do you mean this is expected?
