Flash Enable. When active (low), the Flash Memory module is enabled on
the local memory map. When inactive, the Flash memory is removed from
the local memory map.
DRAM Enable. When active (low), the DRAM module is enabled on the
local memory map. When inactive, the DRAM is removed from the
local memory map.
Not implemented
Flash Configuration Enable. When asserted (low), the Hard Reset
configuration held in BCSR0 is NOT driven on the data bus during Hard
Reset. Also, configuration data held at the 1’st word of the Flash Memory is
driven to the data bus during Hard Reset.
Not implemented
RS232 Port 1 Enable. When asserted (low), the RS232 Port 1 transceiver
is enabled. When negated, the transceiver is in standby mode and the
relevant MPC Communication Port pins become available for off-board use
via the expansion connectors.
PC Card Enable. When asserted (low), the on-board PCMCIA channel is
enabled, i.e. address and strobe buffers are enabled to / from the card.
When negated, all buffers to / from the PCMCIA channel are disabled
allowing off-board use of its associated lines.
PC Card VCC Select 0. These signals, in conjunction with PCCVCC1,
determine the voltage applied to the PCMCIA card’s VCC. Possible values
are 0 / 3.3 / 5 V. For line encoding and associated voltages see
12. "PCCVCC(0:1) Encoding" on page 55
PC Card VPP. These signals determine the voltage applied to the PCMCIA
card’s VPP. Possible values are 0 / 5 / 12 V. For line encoding and
associated voltages see
page 55
DRAM Half Word. When active (low), and the steps listed in
"DRAM 16-Bit Operation" on page 38
wide. When inactive, the DRAM is 32-bit wide.
RS232 Port 2 Enable. When asserted (low), the RS232 Port 2 transceiver
is enabled. When negated, the transceiver enters standby mode and the
relevant MPC Communication Port pins become available for off-board use
via the expansion connectors.
SDRAM Enable. When active (high), the SDRAM module is enabled on the
local memory map. When inactive, the SDRAM is placed in low-power
mode.
