The position manager solutions for absolute encoders leverage a peripheral block on the F28004x and other C2000 MCUs called the configurable logic block (CLB). The CLB works with other peripherals on-chip to create more valuable functions that otherwise might require external logic devices such as a complex programmable logic device (CPLD) or a field-programmable gate array (FPGA).
In position manager solutions, coupling the CLB with a serial port creates solutions for EnDat2.2, bidirectional/serial/synchronous (BiSS), Tamagawa
T-format and other serial encoder standards. The CLB on the F28004x has enough capability to implement two channels of most protocols.
