Programmer Board for AZT70/71
CAP CONTROL (CLK)
The logic level of the CLK input controls the source of the capacitance set commands. If the CLK pin is high, the
capacitance value follows the register contents selected through the ‘Set Capacitance’ button. If the CLK pin is low, the
capacitance value follows the non-volatile EEPROM contents set through the ‘Program EEPROM’ button. The ‘Cap
Control (CLK)’ field shows the state of the CLK input, either ‘Register’ or ‘EEPROM.’
WRITE OPERATIONS
Pressing the ‘Set Capacitance’ button places the contents of the ‘C_hi’, ’C_mid’, and ’C_lo’ binary bit fields into the internal
AZT70/71 registers. The ‘C_hi’ bit field has no effect for the AZT70 since only the AZT71 contains the C_hi selectable
capacitor.
Pressing the ‘Program EEPROM’ button erases the part, and then programs the EEPROM with the contents of C_hi
(AZT71 only), C_mid, and C_lo.
