• Manufacturer Part Number: MAS9191EB
• Description: EVALUATION BOARD
• Manufacturer: MAS

SYSTEM REQUIREMENTS
For the complete evaluation of MAS9191A, MAS9129 and MS8323 ICs the following equipment is needed:
START UP
Connect the supply voltage or a battery to plus and
minus battery terminals. Turn on switch S1 to power
up the board. The power consumption of the
MAS9129 regulators can be measured by inserting an
ammeter between the pins at CM1 and CM2. After
powering up the system, the installed evaluation
software sets up and the evaluation board is now
ready for use. The power down modes of MAS9191A
are controlled by register 07
set by entering Register Write. See the Register write
EVALUATION SOFTWARE
The evaluation software has the following features:
- write function for changing the values of the MAS9191A registers
- read function for reading the values of the MAS9191A status registers
- message send
- message receive
A keypad serves as the software interface.
The key definitions are as follows:
- BACKWARD = 4
- TOGGLE
- FORWARD
- EXIT
- ENTER
- UP
- DOWN

function in the next section. Rough testing of the
microphone, earphone, and buzzer interfaces can be
done with the MAS9191A internal loop back modes.
For more detailed evaluation, a radio test set is
needed. The board is assembled so that the micro
controller will operate at 8.0 MHz. The micro controller
can also be operated at 4.8 MHz by inserting jumper
P6 and disconnecting parts X2, R23, C50 and C51.
Current consumption of MAS9191A is measured at
jumper CM3.
After a reset the internal registers of the MAS9191A
are set to zero and the program returns to the main
menu, which will display the following message on the
LCD:
