Texas Instruments TMS320F2837 D Series User Manual

Advisory HRPWM: HRCNFG Register Reads and Bit-Wise Writes
Revisions Affected
0, A
Details For even-numbered HRPWM modules (2, 4, 6, and 8), HRCNFG register reads return all
0s instead of the actual register contents. Full register writes to HRCNFG do work.
For odd-numbered HRPWM modules (1, 3, 5, and 7), HRCNFG register reads work
properly.
Workarounds Do not perform bit-wise (read-modify-write) writes using the ‘HRCNFG.bit’ register
structures on even-numbered HRPWM modules. This would result in the clearing of other
bits in the HRCNFG register.
Do not perform bit-wise writes to HRCNFG using the debugger window on even-
numbered HRPWM modules. This would result in the clearing of other bits in the
HRCNFG register.
Do not read the even-numbered HRPWM module registers or use the contents in any
software.
Only modify the entire register with ‘HRCNFG.all’ when writing to the even-numbered
HRPWM module registers.
Advisory SYSBIOS in ROM References Different Flash Sector (Changed From Sector A to
Sector B)
Revisions Affected
0, A
Details This advisory applies only to applications using SYSBIOS components available in ROM.
The Flash memory region referenced by the SYSBIOS in ROM has changed from Sector
A to Sector B.
Workarounds The linker command file should be changed as follows:
• On silicon revisions 0 and A, use Sector A:
– SYSBIOS_FLASH: origin = 0x080010, length = 0x0007BE
• On future silicon revisions, use Sector B:
– SYSBIOS_FLASH: origin = 0x082000, length = 0x000824
Advisory McBSP: McBSP Transmit in SPI Slave Mode
Revisions Affected
0, A
Details When using the McBSP peripheral in SPI Slave mode, the data transmitted to the Master
(SOMI) is incorrect.
McBSP in SPI Slave mode receives data properly from the master.
Workarounds Do not transmit data using SPI Slave mode of the McBSP.
