Cyclic Redundancy Check
Memory Cyclic Redundancy Check
UART Mode
To ensure transmitted and received data is free of errors, the OCD transmits an 8-bit cyclic
redundancy check (CRC) at the end of each command. The CRC is enabled after the OCD
is initialized, it is not sent with the first read revision command. This CRC is disabled by
clearing the CRCEN bit of the DBGCTL register.
The CRC is reset at the beginning of each command and is computed on the data received
from and sent to the host. The CRC is calculated using the ATM-8 HEC polynomial
x
first. The resulting CRC is reversed and inverted. The check value is
The read memory CRC command computes the CRC on memory in 4K blocks, up to 4K
blocks at a time (16M of data). The Memory CRC is computed using the 16-bit CCITT
polynomial
polynomial LSB first. The resulting CRC is reversed and inverted. The check value is
F0B8h
When the OCD is disabled, the DBG pin is used as a single pin half-duplex UART. When
the serial interface is in UART mode, data received on the single wire bus is written to the
Receive Data Register. Data written to the Transmit Data Register is transmitted on the
single wire bus. In UART mode, the auto-baud hardware is used to configure the BRG, or
the baud rate registers are written to set a specific baud rate.
The UARTEN control bit must be set to 1 to use the serial interface as a UART. Clearing
the UARTEN control bit to zero will prevent data received on the DBG pin from being
written to the Receive Data Register. Clearing the UARTEN control bit to zero also pre-
