Description
1
PWR
V
DD
---
Digital supply voltage (+5V). There are 2 V
DD
pins, both of
which must be connected.
2
TB
ECB5
1
---
EDAC Check Bit 5. Asserting the EDACEN pin will cause the
error detection and correction engine to pass the EDAC Check
Bit 5 through pin 2 of the UT80CRH196KD.
3
TDI
NMI
High
Non-Maskable Interrupt. A positive transition causes a vector
through the NMI interrupt at location 203Eh. Assert NMI for at
least 1 state time to guarantee acknowledgment by the interrupt
controller.

TI
P0.3
---
Port 0 Pin 3. An input only port pin that is read at location 0Eh
in HWindow 0.
TB
ECB4

EDAC Check Bit 4. Asserting the EDACEN pin will cause the
error detection and correction engine to pass the EDAC Check
Bit 4 through pin 4 of the UT80CRH196KD.
5
TI
P0.1
---
Port 0 Pin 1. An input only port pin that is read at location 0Eh
in HWindow 0.
TB
ECB3
1
---
EDAC Check Bit 3. Asserting the EDACEN pin will cause the
error detection and correction engine to pass the EDAC Check
Bit 3 through pin 5 of the UT80CRH196KD.
6
TI
P0.0
---
Port 0 Pin 0. An input only port pin that is read at location 0Eh
in HWindow 0.
TB
ECB2
1

EDAC Check Bit 2. Asserting the EDACEN pin will cause the
error detection and correction engine to pass the EDAC Check
Bit 2 through pin 6 of the UT80CRH196KD.
