我用的是MSP432P401R，我使用官方的範例msp432p401x_euscib0_spi_09撰寫SPI，但我的設備需要將SPI調整為polarity low和'Phase high ，請問我這樣更改是否正確?
WDT_A->CTL = WDT_A_CTL_PW | // Stop watchdog timer
WDT_A_CTL_HOLD;
P1->OUT &= ~BIT0;
P1->DIR |= BIT0; // Set P1.0 LED
P1->SEL0 |= BIT5 | BIT6 | BIT7; // Set P1.5, P1.6, and P1.7 as
// SPI pins functionality
EUSCI_B0->CTLW0 |= EUSCI_B_CTLW0_SWRST; // Put eUSCI state machine in reset
EUSCI_B0->CTLW0 = EUSCI_B_CTLW0_SWRST | // Remain eUSCI state machine in reset
EUSCI_B_CTLW0_MST | // Set as SPI master
EUSCI_B_CTLW0_SYNC | // Set as synchronous mode
//EUSCI_B_CTLW0_CKPL | // Set clock polarity high
EUSCI_B_CTLW0_CKPH | //Phase high
EUSCI_B_CTLW0_MSB; // MSB first
EUSCI_B0->CTLW0 |= EUSCI_B_CTLW0_SSEL__ACLK; // ACLK
EUSCI_B0->BRW = 0x01; // /2,fBitClock = fBRCLK/(UCBRx+1).
EUSCI_B0->CTLW0 &= ~EUSCI_B_CTLW0_SWRST;// Initialize USCI state machine
