Timers are used for scheduling the different activities within the system. Timers generates interrupt in system and Operating system(OS) Schedules different Timers and maps them to different Interrupt Service Routine (ISR) to start on different interrupts. It can happen before starting a activity or application, OS configures a timers and give control to application to operate. On Interrupt trigger a interrupt, ISR kicks in and passes control back to OS.
A Miss Function on this block can make system to mis-behave a lot. These section explains issues with normal timers and benefits of this high stable timers over conventional timers.
-The Problem with Current Technology
Timers carry large counters, Registers, clocks pre-scalers and synchronizations and all these are built by Simple Components which do not have any stability.
If the SOC is exposed to different hazards like radiations, sparks or other events. These logics can be corrupted within counters and registers carrying configuration.
This may result in corruption in stored configurations or counters or data or control passing by and can make interrupts to be generated fast or slower rate or even stopped.
If system gets faster interrupt, then expected will make control to passed back to Operating system(OS) from the application or much before the application actually able to complete the task. This make system to not able to perform the required task.
if interrupts generation is slowed down, will keep the OS waiting much longer to get control and application work is finished long back. This can make system to slow down or Hang.
-The Solution
High Stable Timers from GreenIPCore can sustain across all system un-stability and misbehavior problems.
This Timers is strengthening system against any kind of dirty Electromagnetic noise and capable of protecting the System operation without disruption.
The Timers is constructed with high stable components. The High Stable Timers shown above will not fail due to any hazardous event.

In some particular application, few pin count but still need chip to chip communication. This IP use one wire bi-direction (open drain) to communication. Just like UART , it is consist of one TX and one RX. User can define their own payload freedomly.
All devices are connecting through open-drain pull high bus. Every device can send data to others actively.

- Analog IC debug
- MCU program port

The Serial Peripheral Interface (SPI) bus, established by Motorola, is a synchronous serial data link. It operates in master/slave and full duplex styles. That is, when a master device initiates a transaction and communicates with a certain slave device, they exchange data bit-by-bit. Furthermore, the single master communication is applied to the SPI bus. Thus, there is always a single master device (with one or more slave devices) on it.
The SPI bus contains 4 wires, with each named SCK, MOSI, MISO and SS_n respectively. You may also find alternative naming conventions elsewhere. The following table lists their functions and directions:
The typical SPI bus architecture is designed as follows:
When the SPI master device wants to communicate with a certain slave device, it asserts the SS_n line of that slave device, and then exchange data using the MOSI and MISO lines based on the toggling SCK line.
With clock polarity (CPOL) and clock phase (CPHA) set to different values, the SPI bus can operate in 4 modes. These modes are listed in the following table, where provide means that the communicating master and slave devices provide data on the MOSI and MISO lines respectively on the other hand, capture means that the communicating master and slave devices capture data on the MISO and MOSI lines respectively:
