Table 4.23 provides a brief description of the ports in the ARMCortexM4CT component. Refer to the processor technical reference manual for more details.
Table 4.23. ARMCortexM4CT ports
| Name | Port protocol | Type | Description |
|---|---|---|---|
auxfault | Value | slave | auxiliary fault status information |
bigend | Signal | slave | configure endianness after a reset |
clk_in | ClockSignal | slave | clock input |
currpri | Value | master | indicates the current execution priority of the processor |
edbgrq | Signal | master | external debug request |
event | Signal | peer | event input and output for wakeup from WFE. This port combines the TXEV and RXEVsignals |
intisr[0-239] | Signal | slave | external interrupt signals |
intnmi | Signal | slave | non-maskable interrupt |
lockup | Signal | master | asserted when processor is in lockup state |
poreset | Signal | slave | asynchronous power-on reset signal input |
pvbus_m | PVBus | master | master port for all memory accesses except those on the External Private Peripheral Bus |
pv_ppbus_m | PVBus | master | master port for memory accesses on the External Private Peripheral Bus |
reset | Signal | slave | asynchronous reset signal input (not debug components) |
sleepdeep | Signal | master | indicates that the processor is in deep sleep |
sleeping | Signal | master | indicates that the processor is in sleep |
stcalib | Value | slave | SysTick calibration value |
stclk | ClockSignal | slave | reference clock input for SysTick |
sysreset | Signal | slave | asynchronous reset signal input |
sysresetreq | Signal | master | system reset request |
ticks | InstructionCount | master | output that can be connected to a visualization component |
dbgen[a] | Signal | slave | enable hardware debugger access |
fpudisable | Signal | slave | disable FPU on next reset |
mpudisable | Signal | slave | disable MPU on next reset |
fpxxc | Value | master | cumulative exception flags from the Floating Point Status and Control Register (FPSCR). This value port combines the five RTL signals FPIXC, FPIDC, FPOFC, FPUFC, FPDZC and FPIOC. |
[a] Since the CT model does not provide a DAP port or halting debug capability, this signal is ignored. | |||
