Description
Reserved. Writes are don’t cares.
Enable MFGPT7 Comparator 2 Output to the Interrupt Mapper. When set high,
this input becomes one of two, ORed together, to form “Unrestricted Sources Z”, bit 7.
The other bit in the ORed pair is bit 11, MFGPT3_C2_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 MFGPT6 Comparator 2 Output to the Interrupt Mapper. When set high,
this input becomes one of two, ORed together, to form “Unrestricted Sources Z”, bit 6.
The other bit in the ORed pair is bit 10, MFGPT2_C2_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.
