4.2.2. C
The operating crystal frequency has been chosen to support the fastest operation with the fastest serial operating speeds.
The value of the crystal is 22.1184MHz.
The following table shows the baud rates and Baud Rate Register (BRR) setting required for each communication rate using
the above default operating speed. It also confirms the resultant baud rate and the bit error rate that can be expected.
* Note: The device used to convert the RS232 serial information to logic signals for the microcontroller is limited to
The default communication rate for the EDK is indicated by the shaded selection.
The user may replace the HC49/U surface mounted AT cut crystal with another of similar type within the operating frequency
of the microcontroller device. Please refer to the hardware manual for the microcontroller for the valid operating range.
Alternatively the user may fit an oscillator module – or provide an external clock source. When providing an oscillator module
or external source it is highly recommended that the load capacitors for the AT crystal are removed from the PCB. These are
physically placed within the PCB outline of the oscillator module for easy location and to ensure they are removed when
using this option.
When changing the crystal frequency the pre-loaded debugging monitor will not function. In this situation the user is
responsible for providing code to evaluate the device away from the default operating speed.
4.2.3. R
This information is provided to allow the replacement of components removed from the board as described in section 4.2.2.
Care must be taken not to damage the tracking around these components. Only use soldering equipment designed for
surface mount assembly and rework.
4.3. SRAM
The SRAM device fitted to the board is a 4Mbit device allowing 256k x 16 operation.
The SRAM is mapped to area 0 via chip select 0 (port PG4), with a usable address range of H’00080000 – H’000BFFFF
using address signals A1 – A18.
Glue logic provides the required SRAM control signals from the H8S/2329 micon.
