USART Asynchronous Communications
CAUTION
The USB port current limit is set to 100 mA. If the target plus PICkit Serial Analyzer
exceeds this current limit, the USB port will turn off. The target may be powered
externally if more power is required.
USART BAUD
Enter the desired USART symbol rate (Baud) in the text box.

Abrt Mac Exe – Enable event marker: abort ‘macro’ execution
Macro Loop – Enable event marker: top of ‘macro’ loop
Mac Lp 65536 – Enable event marker: ‘macro’ loop count overflow (i.e., 65536)
Mac Lp Done – Enable event marker: ‘macro’ loop iterations complete
Timeout Timer1 – Enable event marker: Timer1 expired
Timeout Timer2 – Enable event marker: Timer2 expired
Status Error – Enable event marker: change in status byte
Read Byte – Enable event marker – read byte
Write Byte – Enable event marker – write byte
Status Error – Enable event marker – change in USART status byte
Break TX – Enable event marker – A “Break” has been transmitted
ADVANCED OPTIONS
? Disable LED2 Default – Disable default LED2 behavior (LED2 = Yellow ‘Target’
LED)
? Disable LED1 Default – Disable default LED1 behavior (LED1 = Red ‘Busy’ LED)
? Enable Switch Test – Enable low level switch test:
? AUX1 Default State – AUX1 communication line – default state ( 0 | 1 )
? AUX2 Default State – AUX2 communication line – default state ( 0 | 1 )
? AUX1 Direction – AUX1 communication line – direction: 1 : input, 0 : output
? AUX2 Direction – AUX2 communication line – direction: 1 : input, 0 : output
? Async Receive Disabled – Received Data is disabled
