Signals and Connections
MC9328MXL Technical Data, Rev. 8
Freescale Semiconductor
5
Bootstrap
BOOT [3:0]
System Boot Mode Select—The operational system boot mode of the i.MXL processor upon system
reset is determined by the settings of these pins.
SDRAM Controller
SDBA [4:0]
SDRAM 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 cycles.
SDIBA [3:0]
SDRAM 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 cycles.
MA [11:10]
SDRAM address signals
MA [9:0]
SDRAM address signals which are multiplexed with address signals A [10:1]. MA [9:0] are selected on
SDRAM cycles.
DQM [3:0]
SDRAM data enable
CSD0
SDRAM Chip-select signal which is multiplexed with the CS2 signal. These two signals are selectable
by programming the system control register.
CSD1
SDRAM Chip-select signal which is multiplexed 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 boot
chip-select by properly configuring BOOT [3:0] input pins.
RAS
SDRAM Row Address Select signal
CAS
SDRAM Column Address Select signal
SDWE
SDRAM Write Enable signal
SDCKE0
SDRAM Clock Enable 0
SDCKE1
SDRAM Clock Enable 1
SDCLK
SDRAM Clock
RESET_SF
Not Used
Clocks and Resets
EXTAL16M
Crystal input (4 MHz to 16 MHz), or a 16 MHz oscillator input when the internal oscillator circuit is shut
down.
XTAL16M
Crystal output
EXTAL32K
32 kHz crystal input
XTAL32K
32 kHz crystal output
CLKO
Clock Out signal selected from internal clock signals.
RESET_IN
Master Reset—External active low Schmitt trigger input signal. When this signal goes active, all
modules (except the reset module and the clock control module) are reset.
RESET_OUT
Reset Out—Internal active low output signal from the Watchdog Timer module and is asserted from the
following sources: Power-on reset, External reset (RESET_IN), and Watchdog time-out.
POR
Power On Reset—Internal active high Schmitt trigger input signal. The POR signal is normally
generated by an external RC circuit designed to detect a power-up event.
