UARTx_WP7816C_T1 field descriptions
Field Description
7–5
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
CWI2 Character Wait Time Integer 2 (C7816[TTYPE] = 1)
Used to calculate the value used for the CWT counter. It represents a value between 0 and 31. This value
is used only when C7816[TTYPE] = 1. See Wait time and guard time parameters .
47.4 Functional description
This section provides a complete functional description of the UART block.
The UART allows full duplex, asynchronous, NRZ serial communication between the
CPU and remote devices, including other CPUs. The UART transmitter and receiver
operate independently, although they use the same baud rate generator. The CPU
monitors the status of the UART, writes the data to be transmitted, and processes
received data.
