; --------------------> LEDRED is indicating the Monitor-Reset state, if
LEDRED = USERRES * FLASHRES * /MONRES ; Mon-reset button pressed
+ /DTR ; or uart-reset (DTR line low)
+ (/PONFLAG * /DEFAULT) ; or Power-on (Default-Mode=Mon)
+ /LEDGRN * /LEDYEL ; (hold-condition)
; --------------------> LEDGRN is indicating the User-Reset state, if
LEDGRN = /USERRES * FLASHRES * MONRES ; User-Reset button pressed
+ (A20 * /A19 * /CS2) ; or Remote-User-reset request
+ /LEDYEL * /LEDRED ; (hold-condition)
; --------------------> LEDYEL is indicating the Flash-Reset state, if
LEDYEL = USERRES * /FLASHRES * MONRES ; Flash-Reset button pressed
+ (/PONFLAG * DEFAULT) ; or Power-on (Default-Mode=Flash)
+ /LEDGRN * /LEDRED ; (hold-condition)
MODE = LEDGRN ; Mode-Pin (MD0) is 1, if User-Reset state, otherwise 0
PG5 = LEDYEL ; Flash-Ind-Pin is 1, if Flash-Reset state, otherwise 0
