Preliminary

5.6.3.1

Flash Memory Command, Data, Address Buffers Empty Interrupt

Priority Level (FMCBE IPL)—Bits 15–14

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

It is 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

5.6.3.2

Flash Memory Command Complete Priority Level

(FMCC 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.

It is 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

5.6.3.3

Flash Memory Error Interrupt Priority Level

(FMERR 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.

It is 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

5.6.3.4
