Circuit Operation

Control-System Circuit
1.4.2.1.1.
CPU Peripherals
• CPU (System clock: 12.288 MHz)......IC601
Data bus: 16bit, Address bus: 23bit
• Flash ROM (512Kbyte)......IC602
Flash memory consists of two areas: boot space and administration space.
Administration program can be rewritten through downloading.
• SRAM (1Mbit)......IC603
Used for the data buffer for CPU work area, and SLT communication.
• Reset
Resets of an MCSLC24 card are roughly classified into the two kinds: ASIC reset and LPR reset.
After the release of the ASIC reset, the LPR reset is released by the soft reset from the side of the main card and the LPR pro-
gram is booted.
Type of reset
Reset method
Specification
ASIC reset
ASIC reset is reset under the AND condition of reset signals (negative logic)
listed below.
Power-on reset
Reset by reset IC
Hard reset from the main bus
Reset by EC_RST signal
Soft reset from the main bus
Released after the specified time
LPR reset
Soft reset from the main bus
Low active
Reset pulse width: 1.6 microseconds or more

• LED Operation status indicating LED (Two colors)
OFF: Fault
Red ON: Fault (RESET included)
Green ON: Normal (Line not in use)
Green Flash (60/minute): Normal (Line in use)
Orange: OUS (Because OUS needs to be controlled by MPR, reset terminal and port control terminal are Red Blinking: OUS to
generate OUS)
• Instantaneous power interruption operation
When instantaneous power interruption is 300msec or less, reset operation is not carried out because the voltage is retained by
the capacitor in the power supply.
After HALT from MPR is detected at the DC power down port, CPU goes into the sleep mode by executing the instruction of
SLEEP.
At the sleep mode, the CPU/Clock enters the halt state while the contents of the register, the internal RAM, and the I/O port are
maintained.
When the instantaneous power interruption is released, HALT is negated, and CPU is recovered to the normal mode by the
detection of IRQ0=L
