Analog Continuous Time Block xx Control 1 Register
The PMux bits control the multiplexing of inputs to the
non-inverting input of the op-amp. There are physically
only 7 inputs.
The 8
th
code (111) will leave the input floating. This is not
desirable, and should be avoided.
The NMux bits control the multiplexing of inputs to the
inverting input of the op-amp. There are physically only 7
inputs.
CompBus controls a tri-state buffer that drives the com-
parator logic. If no PSoC block in the analog column is
driving the comparator bus, it will be driven low externally
to the blocks.
AnalogBus controls the analog output bus. A CMOS
switch connects the op-amp output to the analog bus.
Analog Continuous Time Block 00 Control 1 Register (ACA00CR1, Address = Bank 0/1, 72h)
Analog Continuous Time Block 01 Control 1 Register (ACA01CR1, Address = Bank 0/1, 76h)
Analog Continuous Time Block 02 Control 1 Register (ACA02CR1, Address = Bank 0/1, 7Ah)
Analog Continuous Time Block 03 Control 1 Register (ACA03CR1, Address = Bank 0/1, 7Eh)
