Buzzer
The PBMCUSLK features an external drive buzzer for audible applications. The buzzer is
connected to a TIMER / PWM port on all current MCU modules. The buzzer is connected
directly to the MCU _PORT connector at MCU_PORT – 13 and does not require an enable
signal similar to the other Connected Features. The buzzer is connected to the MCU_PORT
through an option header at UFEA -2 (PB).
Connected Feature Enable
Each Connected Feature is enabled by applying the appropriate signal level to the enable line
for that feature set. Each connected feature group may be enabled or disabled independently
of the other groups.
Each Connected Feature is enabled as a group; i.e. all push-buttons are enabled or disabled,
all LED’s are enabled or disabled, the POT is enabled or disabled.
Table 8: User Feature Enable
To prevent signal corruption, each enable signal may be isolated from the MCU_PORT. An
option header at UFEA
individually. This allows the GPIO port signal applied to the Connected Feature Enable to be
used for other purposes.
