Hi TI Engineers,
I found some problems in OMAP35x document (spruf98_t) in GPMC section. I hope you can help to clarify them.
1- Page 1111 : for Figure 11-20 there are two definition to calculate the value of WRCYCLETIME that are not same :
"Total access time (WRCYCLETIME) corresponds to WRACCESSTIME plus the address hold time
from nCS deassertion, plus time from WRACCESSTIME to CSWROFFTIME.
– WRCYCLETIME is defined in the GPMC.GPMC_CONFIG5_i register.
– In Figure 11-20, the WRCYCLETIME programmed value equals WRCYCLETIME0 +
WRCYCLETIME1."
actually the value of WRCYCLETIME with first formula in much larger then the value with second formula!
2- Page 1109. Figure 11-19 is in nonmultiplexed mode as stated in line 5 of this page (MUXADDDATA bit at 0 (nonaddress/data-multiplexed device)) , but in figure the address still multiplexd with data and nADV is generated!
3- Page 1110. Figure 11-20 is for Synchronous Multiple (Burst) Write but nWE signal in high (inactive) during write process!
I will appreciate if somebody clarify these problems.
regards.
