10.13.4 Analog Output Buffer Control Register
Analog Output Buffer Control Register (ABF_CR, Address = Bank 1, 62h)
10.14 Analog Modulator
The user has the capability to use the Analog Switch
Cap Type A PSoC Blocks in Columns 0 and 2 as ampli-
tude modulators. The Analog Modulator Control Register
(AMD_CR) allows the user to select the appropriate
modulating signal. When the modulating signal is low,
the polarity follows the setting of the ASign bit set in the
Analog Switch Cap Type A Control 0 Register
(ASAxxCR0). When this signal is high, the normal gain
polarity of the PSoC block is inverted.
