Multi-Function General Purpose Timer
Note 1. Compare 2 Value must be set to all 1s for pulse density modulation.

The Working power domain logic consists of the Local Bus
Interface, Control Logic, MSRs, and NMI, IRQ, and Reset
Output Events.
When Event mode is enabled, the NMI, IRQ, and Reset
Output Events logic gathers the event outputs of all eight
MFGPTs and then generates the interrupt and resets out-
puts based on MSR settings. The interrupt outputs go to
the PIC that can then trigger an IRQ or ASMI. Note that
MFGPT6 and MFGPT7 cannot trigger reset. These outputs
are controlled by MSR bits, and the NMI output can be fur-
ther controlled by the MSB of I/O Address 070h.

The asynchronous internal Standby State signal will dis-
able/enable the Working power domain interface immedi-
ately. Therefore, any bus operation active at that time will
have an indeterminate result.
