Overview
Clock signal (CLK)
The AT89EVK-01 board is soldered on the customer application by using the SO plug. If
there is a problem to connect the AT89EVK-01 board on the SO plug, connectors can
be added to lift the board.
Figure 2-1. General Description
Input signals of the TDA8004 footprint are connected to AT83C24.
Output signals of the TDA8004 footprint are provided by AT83C24.
The program stored in the Flash memory configures the AT83C24 registers once after
the reset. The functionalities of the TDA8004 are provided by the AT83C24.
Remarks:
The AT89EVK-01 board needs a clock signal. The AT89EVK-01 board needs a clock
signal for T89C5121 (XTAL1 pin) and for AT83C24 (CLK pin).
The AT89EVK-01 board power supply comes from the TDA8004 footprint.
The program stored in the Flash memory configures the AT83C24 registers once after
the reset.
