Signals and Connections
MC9328MX1 Technical Data, Rev. 7
Freescale Semiconductor
5
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.
JTAG
TRST
Test Reset Pin—External active low signal used to asynchronously initialize the JTAG controller.
TDO
Serial Output for test instructions and data. Changes on the falling edge of TCK.
TDI
Serial Input for test instructions and data. Sampled on the rising edge of TCK.
TCK
Test Clock to synchronize test logic and control register access through the JTAG port.
TMS
Test Mode Select to sequence the JTAG test controller’s state machine. Sampled on the rising edge of
TCK.
