12.2
The following registers are only associated with the Analog Bus Mux in the CY8CTMG20x and CY8CTST200 PSoC devices
and are listed in address order. Each register description has an associated register table showing the bit structure for that
register. Register bits that are grayed out throughout this document are reserved bits and are not detailed in the register
descriptions that follow. Always write reserved bits with a value of ‘0’.
12.2.1
The Analog Mux Port Bit Enable Registers (MUX_CR0,
MUX_CR1, MUX_CR2, MUX_CR3, and MUX_CR4) control
the connection between the analog mux bus and the corre-
sponding pin.
Bits 7 to 0: ENABLE[7:0]. The bits in these registers
enable connection of individual pins to the analog mux bus.
Each I/O port has a corresponding MUX_CRx register.
