Detail of Block Description
• CPU block
Configuration: IC5(CPU), IC8 (reset IC), IC6 (spread clock IC), X2 (CPU source clock), X1 (clocking clock) etc.
Function: (IC10)
Generates the select signal in accordance with the memory map and operates read/write of data between each peripheral.
Controls the DMA transfer between USB I/F or built-in serial controller and memory.
Operates input/output control of each I/O signal in accordance with the program.
Contains the built-in clock function (battery backup) with the source clock X1 (32.768 kHz).
(IC8)
Monitoring the power voltage, it generates a reset signal when the voltage drops under the constant value (2.9Vtyp) or when
the reset switch is pressed down.
(IC6)
To reduce unnecessary radiation, it generates the clock with the constant blurring mainly X2 clock output (16.384 MHz).

with ASIC mounted to each option card via EC bus and controls the option card.
Controls CT bus (HW clock 8.192MHz, 8 highway, 128 timeslot) for TSW function.
(A detailed description of TSW will be added later.)
Controls the conference call for 3 people x ~8 parties ~ 8 people x ~3 parties.
Generates single and DTMF tone in any highway and timeslot.
Provides the digital gain control function by data conversion.
Provides some I/O ports for CODEC channel pulse generation, modem encoding rule setting and music on hold switching and
is controlled by CPU.
