Signal Descriptions and Pin Assignments
Bootstrap
BOOT [3:0]
System Boot Mode Select—The operational system boot mode of the MC9328MX1 upon
system reset is determined by the settings of these pins.
SDRAM Controller
SDBA [4:0]
SDRAM/SyncFlash non-interleave mode bank address multiplexed with address signals
A [15:11]. These signals are logically equivalent to core address p_addr [25:21] in
SDRAM/SyncFlash cycles.
SDIBA [3:0]
SDRAM/SyncFlash interleave addressing mode bank address multiplexed with address
signals A [19:16]. These signals are logically equivalent to core address p_addr [12:9] in
SDRAM/SyncFlash cycles.
MA [11:10]
SDRAM address signals
MA [9:0]
SDRAM address signals which are multiplex with address signals A [10:1]. MA [9:0] are
selected on SDRAM/SyncFlash cycles.
DQM [3:0]
SDRAM data enable
CSD0
SDRAM/SyncFlash Chip Select signal which is multiplexed with the CS2 signal. These
two signals are selectable by programming the system control register.
CSD1
SDRAM/SyncFlash Chip Select signal which is multiplex with CS3 signal. These two
signals are selectable by programming the system control register. By default, CSD1 is
selected, so it can be used as SyncFlash boot chip select by properly configuring BOOT
[3:0] input pins.
RAS
SDRAM/SyncFlash Row Address Select signal
CAS
SDRAM/SyncFlash Column Address Select signal
SDWE
SDRAM/SyncFlash Write Enable signal
SDCKE0
SDRAM/SyncFlash Clock Enable 0
SDCKE1
SDRAM/SyncFlash Clock Enable 1
SDCLK
SDRAM/SyncFlash Clock
RESET_SF
SyncFlash Reset
Clocks and Resets
EXTAL16M
Crystal input (4 MHz to 16 MHz), or a 16 MHz oscillator input when internal oscillator
circuit is shut down.
XTAL16M
Crystal output
EXTAL32K
32 kHz crystal input
XTAL32K
32 kHz crystal output
