Preliminary

5.6.5.2

SPI 1 Transmit Empty Interrupt Priority Level (SPI1_XMIT IPL)—

Bits 13–12

This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 0 through 2.

They are disabled by default.

•

00 = IRQ disabled (default)

•

01 = IRQ is priority level 0

•

10 = IRQ is priority level 1

•

11 = IRQ is priority level 2

5.6.5.3

SPI 1 Receiver Full Interrupt Priority Level (SPI1_RCV IPL)—

Bits 11–10

This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 0 through 2.

They are disabled by default.

•

00 = IRQ disabled (default)

•

01 = IRQ is priority level 0

•

10 = IRQ is priority level 1

•

11 = IRQ is priority level 2

5.6.5.4

Reserved—Bits 9–6

This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.

5.6.5.5

GPIOA Interrupt Priority Level (GPIOA IPL)—Bits 5–4

This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 0 through 2.

They are disabled by default.

•

00 = IRQ disabled (default)

•

01 = IRQ is priority level 0

•

10 = IRQ is priority level 1

•

11 = IRQ is priority level 2

5.6.5.6

GPIOB Interrupt Priority Level (GPIOB IPL)—Bits 3–2

This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 0 through 2.

They are disabled by default.

•

00 = IRQ disabled (default)

•

01 = IRQ is priority level 0

•

10 = IRQ is priority level 1

•

11 = IRQ is priority level 2

5.6.5.7

GPIOC Interrupt Priority Level (GPIOC IPL)—Bits 1–0

This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 0 through 2.

They are disabled by default.
