System Control CPLD
TE0841-01 hassmall has a small 256 Macrocell CPLD on-board to perform some basic System Control functionality.
...
In minimal standard function the CPLD sets PUDC value (low or high), and forwards reset, JTAG and LED to/from the FPGA.
System Control CPLD can implement many advance functions as well, some list of possible extra functionality:
- Programmable Watchdog
- Power up time counter
System Control IP Core
This is small IP Core to help setting up fixed hardware functions on TE0841 and to communicate with the System Controller CPLD. This care provides optional Interface ports to attach to System Controller (MicroBlaze MCS based Microcontroller running System Control Firmware).
