Resetting the System ACE CF Controller
There are three types of reset of the System ACE CF con-
troller:
1. Power-on-reset (POR)
2. Device reset
3. Configuration controller reset
Power-on-Reset (POR)
The POR circuit is used to reset the entire System ACE CF
controller device upon device power up. The built-in POR
Table 2: POR Functionality
1. The POR_BYPASS pin should be held at a static ‘0’ or ‘1’ while the System ACE CF controller is receiving power.
2. Hold at ‘1’ for at least one microsecond.
Device-Level Reset
The entire System ACE CF controller device can be reset by
asserting the RESET pin of the System ACE CF Controller.
The timing associated with this operation is shown in
Figure 5, page
CompactFlash Card Reset
The CompactFlash card can be issued a soft reset com-
mand by issuing a ResetMemCard command through the
CMD[2:0] bits in the
address 014h-15h, WORD address 0Ah), page
Configuration Controller Reset
The configuration controller portion of the System ACE CF
device can be reset by asserting CFGRESET = ‘1’ in the
CONTROLREG MPU register (CFGRESET is bit 7). Assert-
ing CFGRESET = ‘1’ will reset the portion of the System
ACE CF device that controls the reading of ACE file data
from the CF card and configuration of the devices con-
nected to the CFGJTAG port. The CFGRESET register is
used in conjunction with the CFGMODE and CFGSTART
pins/registers to control this configuration process.
