up.
Used as the program area and the CPU work area after start-up.
Made a direct bus connection to CPU due to high-speed action
(bus clock 66MHz).
(IC309, IC310, IC311)
Generates each memory select signal from the memory area
select signal and upper address. Generates the write signal and
upper/lower byte select signal.
- USB block
Configuration: IC204 (USB I/F), X201 (source clock: 12.000MHz),
CN209 (USB connector) and so on.
Function: Connects to the USB host system (mainly PC) via
CN209 (B type connector) as a USB device and makes data
transfer by max.11Mbps. DMA function of CPU is utilized to
transfer the data.
- SD card block
Configuration: IC205 (SD card I/F), IC209, X202(20MHz), CN211 (SD
card connector) and so on.
Function: Loads the main program and the system data from the
SD card connected to CN211 by 10Mbps. Restores the system
data periodically.
- MOH/PAGING block
Configuration: IC405, IC406 (CODEC), IC408, IC409 (OP Amp),
IC410 (Melody IC), Q407~Q410 (transistor), JK401~JK404 (pin jack)
and so on.
Function: The external music on-hold 1 is input from JK404 and is
A/D converted in IC405 via AGC (Auto Gain Control) circuit, which
consists of IC408, Q407, Q409 and other CR, and then is
connected to the call line HW. Likewise the external music on-
hold 2 is input from JK403 and is made A/D conversion in IC406
via AGC (Auto Gain Control) circuit, which consists of IC409,
Q408, Q410 and other CR, and then is connected to the call line
HW. The external music on-hold 2 and IC410 is exclusively
connected to IC406 input (by software control).
The various tones & DTMF tone and the voice data generated in
IC102 (ASIC) are made D/A conversion in IC405 and IC406. They
