Register Address:
SPI Base + 09h
Register Name: MMC Control Register
Default Value:
--------
Attribute:
Read Only
Bit Description Read/Write
0
MMC_DETECT#: This bit reflects MMC DETECT state and it is used by
MMC to indicate the AMC chassis insertion status.
0: State is low to indicate that EVM is inserted into the AMC chassis.
1: State is high to indicate that the EVM is not insterted
RO
1
MMC_RSTSTAT#: This bit reflects DSP RESETSTAT state and FPGA
will drive the same logic value on the MMC_RSTSTAT# pin (to MMC).
0 : State is low and FPGA drives MMC_RSTSTAT# low to MMC
1 : State is high and FPGA drives MMC_RESETSTAT# high to MMC
RO
2
MMC_POR_IN_AMC#: This bit reflects MMC_POR_IN_AMC# state
and it is used by the MMC to trigger a Power-On sequence & reset
event.
0: State is low to trigger a Power-On sequence & reset event.
1: State is high and the FPGA stays in current state.
RO
3
MMC_WR_AMC#: This bit reflects MMC_WR_AMC# state and it is
used by the MMC to trigger a warm reset event.
0: State is low to trigger a warm reset event.
1: State is high and the FPGA stays in current state
