(default)
3.3 V is supplied as the target power-supply voltage.
(6) Jumper block: JP22 (FLMD0)
JP22 (FLMD0)
Specification
Open-circuit
(default)
FLMD0 pin = “L” (pulled down)
Short-circuit
FLMD0 pin = “H” (pulled up)
(7) Jumper block: JP23 (FLMD1)
JP23 (FLMD1)
Specification
Open-circuit
(default)
FLMD1 pin = “L” (pulled down)
Short-circuit
FLMD1 pin = “H” (pulled up)
(8) Silk-screened mark for aligning the position of pin 1
When connecting the emulation adapter, match the position of the sticker for aligning the position of pin
1 on the emulation adapter with that of the silk-screened mark for aligning the position of pin 1 on the
base board.
