8.1.1.1
Unit Description
The Power-up logic required on ATCA 8310 resides in a CPLD. It implements these functions:
z
Enable all onboard DC-DC converter
z
Fulfill Power up timing sequence requirements
z
Supervision of all onboard powers
z
IPMC latch registers
z
SPI Master interface to forward communication from IPMC to the Glue FPGA
z
IPMC SPI Slave interface with two chip selects to communicate with the Glue FPGA and to
access CPLD Registers.
z
SPI Slave interface to Glue FPGA to access CPLD registers. For example to update the CPLD
update via SPP.
z
The CPLD clock uses the internal 22 MHz clock oscillator (+- 18%)
8.1.2
CPLD Registers
The CPLD Registers are accessible by the SPP via the CPLD SPI interface and or by the IPMC via
H8S SPI interface. The CPLD supports up to 32 registers.
