4.4.2 INT Signal Functions
The INT signals have these multiple functions:
• If the SZEN bit in the chip configuration register is set, then
INT[7:6] will be used to reflect the state of the TSIZ[1:0] signals
from the M•CORE.
• If the PSTEN bit in the chip configuration register is set, then
INT[5:2] will be used to reflect the state of the PSTAT[3:0] signals
from the M•CORE.
NOTE:
If the SZEN or PSTEN bits are set during emulation mode, then the
corresponding edge port INT functions are lost and will not be emulated
externally.
The default reset values for PUPSCI1 and PUPSCI0 will be 0. Thus, the
pullup function is disabled by default.
4.5 Signal Descriptions
This subsection provides a brief description of the signals. For more
detailed information, reference the module section.
4.5.1 Reset Signals
These signals are used to either reset the chip or as a reset indication.
4.5.1.1 Reset In (RESET)
This active-low input signal is used as an external reset request.
4.5.1.2 Reset Out (RSTOUT)
This active-low output signal is an indication that the internal reset
controller has reset the chip. When RSTOUT is active, the user may
drive override options on the data bus. RSTOUT is three-stated in
phase-lock loop (PLL) test mode.
RSTOUT may also be used to reflect an indication of an internal interrupt
request.
