FUNCTIONAL DESCRIPTION
CORE: Core module interconnects all the sub-modules in the CXPI Master IP. Ports of core module are the top level ports for the CXPI Master IP.
CSR: CSR module has all the Control and status registers. This module has RX FIFO for store response frame from slave. Has TX FIFO for transmit Header and data. This block contains interrupt enable and status registers.
APPS: Apps module implements and controls application/transport/network layer. Implements CRC logic, retry logic and Sleep/Wakeup. This block controls transmit and receive FSM.
TFSM: This block implements the UART transmit statemachine and PWM encoder. Also this block checks the collosion.
RFSM: This block implements the UART receive state machine and PWM decoder.
PRESCALER: Prescaler Module is used to divide the i_clk clock based on the given prescaler value to derive the serial clock for transmission and sampling of the frame. The clock divider is fractional clock divider.
