Description
Reserved. Writes are don’t care; reads return 0.
Description
Enable MFGPT4 Comparator 1 Output to the Interrupt Mapper. When set high,
this input becomes one of two, ORed together, to form “Unrestricted Sources Z”, bit 0.
The other bit in the ORed pair is bit 0, MFGPT0_C1_IRQM. The Unrestricted
Sources Z are detailed in Table 4-14 "IRQ Map - Unrestricted Sources Z" on page
105. When cleared low, this MFGPT output does not contribute to the Unrestricted
Sources Z interrupt.
Enable MFGPT3 Comparator 1 Output to the Interrupt Mapper. When set high,
this input becomes one of two, ORed together, to form “Unrestricted Sources Z”, bit 3.
The other bit in the ORed pair is bit 7, MFGPT7_C1_IRQM. The Unrestricted
Sources Z are detailed in Table 4-14 "IRQ Map - Unrestricted Sources Z" on page
105. When cleared low, this MFGPT output does not contribute to the Unrestricted
Sources Z interrupt.
Enable MFGPT2 Comparator 1 Output to the Interrupt Mapper. When set high,
this input becomes one of two, ORed together, to form “Unrestricted Sources Z”, bit 2.
The other bit in the ORed pair is bit 6, MFGPT6_C1_IRQM. The Unrestricted
Sources Z are detailed in Table 4-14 "IRQ Map - Unrestricted Sources Z" on page
105. When cleared low, this MFGPT output does not contribute to the Unrestricted
Sources Z interrupt.
Enable MFGPT1 Comparator 1 Output to the Interrupt Mapper. When set high,
this input becomes one of two, ORed together, to form “Unrestricted Sources Z”, bit 1.
The other bit in the ORed pair is bit 5, MFGPT5_C1_IRQM. The Unrestricted
Sources Z are detailed in Table 4-14 "IRQ Map - Unrestricted Sources Z" on page
105. When cleared low, this MFGPT output does not contribute to the Unrestricted
Sources Z interrupt.
Enable MFGPT0 Comparator 1 Output to the Interrupt Mapper. When set high,
this input becomes one of two, ORed together, to form “Unrestricted Sources Z”, bit 0.
The other bit in the ORed pair is bit 4, MFGPT4_C1_IRQM. The Unrestricted
Sources Z are detailed in Table 4-14 "IRQ Map - Unrestricted Sources Z" on page
105. When cleared low, this MFGPT output does not contribute to the Unrestricted
Sources Z interrupt.
