SW1CNV
SS
BYTE SW2
SW3XOUT
Pulls down pin CNVSS of MCU with a resistance of
33 kΩ. Be sure to set this when the target system
is not connected in single-chip mode or memory
expansion mode.
Connects pin CNV
SS to the target system. Be sure
to set this when the target system is connected.
Pulls up pin CNVSS of MCU with a resistance of 33
kΩ. Be sure to set this when the target system is
not connected in microprocessor mode.
Connects pin BYTE to the target system. Be sure
to set this when the target system is connected.
Pulls up pin BYTE of MCU with a resistance of 33
kΩ. Be sure to set this when the target system is
not connected in 8-bit bus mode.
Does not connect pin XOUT of MCU to the target
system.
Pulls down pin BYTE of MCU with a resistance of
33 kΩ. Be sure to set this when the target system
is not connected in 16-bit bus mode.
Connects pin X
OUT of MCU to the target system.
