PWMA0
ISA0
top/bottom pulse width correction in complementary channel
operation for PWMA.
FAULTA0
selected PWMA outputs in cases where fault conditions originate
off-chip.
Reset—This input is a direct hardware reset on the processor.
When RESET is asserted low, the controller is initialized and placed
in the Reset state. A Schmitt trigger input is used for noise immunity.
When the RESET pin is deasserted, the initial chip operating mode
is latched from the EXTBOOT pin. The internal reset signal will be
deasserted synchronous with the internal clocks, after a fixed
number of internal clocks.
To ensure a complete hardware reset, RESET and TRST should be
asserted together. The only exception occurs in a debugging
environment when a hardware device reset is required and it is
necessary not to reset the OnCE/JTAG module. In this case, assert
RESET, but do not assert TRST.
External Boot—This input is tied to V
off-chip memory. Otherwise, it is tied to V
