FUNCTIONAL DESCRIPTION
12-bit PWM/BRM static DAC output.
Sink/Source current 8 mA/-8 mA.
With slew rate control and output delay:
1. Delay about 5ns: BSDAC1
2. Without delay: BSDAC0.
---------------------------------------------------------
* In the Flash/RAM-test mode
(when the chip is in reset state):
BSDAC0: A8 input.
* In the functional test mode
(CPU executes out of ext. program memory):
BSDAC0: A8 output.
8-bit PWM dynamic DAC output.
Sink/Source current 8 mA/-8 mA.
With slew rate control and output delay:
1. Delay about 5 nS: DDAC1.
2. Delay about 10 nS: DDAC2.
3. Without delay: DDAC0.
---------------------------------------------------------
* In the Flash/RAM-test mode
(when the chip is in reset state):
DDAC0: A9 input.
* In the functional test mode
(CPU executes out of ext. program memory):
DDAC0: A9 output.
12-bit PWM/BRM dynamic DAC output.
Sink/Source current 8mA/-8mA.
With slew rate control.
---------------------------------------------------------
* In the Flash/RAM-test mode
(when the chip is in reset state):
BDDAC: A10 input.
* In the functional test mode
(CPU executes out of ext. program memory):
BDDAC: A10 output.
