COMMENT
JP16
Port 4 tri-state
(at CPLD)
When the middle pin of this 3 position jumper is set to VCC, the
CPLD passes traffic from the DS3174 to the DS33Z44. When the pin
is set low, the CPLD tri-states this port.
JP17
Port 2 tri-state
(at CPLD)
When the middle pin of this 3 position jumper is set to VCC, the
CPLD passes traffic from the DS3174 to the DS33Z44. When the pin
is set low, the CPLD tri-states this port.
JP18
Port 3 tri-state
(at CPLD)
When the middle pin of this 3 position jumper is set to VCC, the
CPLD passes traffic from the DS3174 to the DS33Z44. When the pin
is set low, the CPLD tri-states this port.
JP19
Port 1 tri-state
(at CPLD)
When the middle pin of this 3 position jumper is set to VCC, the
CPLD passes traffic from the DS3174 to the DS33Z44. When the pin
is set low, the CPLD tri-states this port.
J243
CPLD loopback
CPLD loopback makes the following connections:
Zrser ← Ztser, Ztden ← 3.3V, Zrden ← 3.3V,
Ztclki ← OscY03, Zrclki ← OscY03
