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:
- Switch Off (not depressed) – blink LED1, LED2 off
- Switch ON (depressed) – blink LED2, LED1 off
? 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
? Clock Polarity – Checked means the polarity is inverted, unchecked means it is
not
