ACCxxCR1
Analog Continuous Time Type C Block Control Register 1
This register is one of four registers used to configure a type C continuous time PSoC block.
The register naming convention for arrays of PSoC blocks and their registers is <Prefix>mn<Suffix>, where m = row index, n
= column index; therefore, ACC01CR1 is a register for an analog PSoC block in row 0 column 1. For additional information,
refer to the
“Register Definitions” on page 426
in the Continuous Time Block chapter.

AnalogBus
Enable output to the analog bus.
0
Disable output to analog column bus.
1
Enable output to analog column bus.
6
CompBus
Enable output to the comparator bus.
0
Disable output to comparator bus.
1
Enable output to comparator bus.

NMux[2:0]
Encoding for negative input select. Note that available mux inputs vary by individual PSoC block. In
this table, only columns ACC00 and ACC01 are used by the 2 column analog PSoC blocks and all
columns are used by the 4 column analog PSoC blocks.
