#105233 - yep... Responding to: ???'s previous message |
Oh yes, I am sorry. I was confused as it is not where I expected it to be - in the Timer2 description, as is in the "normal" 8052 datasheets. Philips placed it - rather illogically - under the POWER-ON FLAG chapter...
However, there still IS something to be cleared. The last section says, it is possible to use the clockout mode simultaneously with baudrate generation. The last sentence says: P89C51RD2 datasheet on page 12 said:
Note, however, that the baud-rate and the Clock-Out frequency will be the same. Now I think this is a nonsense. The "normal" '52 datasheet say (I quote from the Intel document): 27238302.pdf on page 155 said:
Note, however, that the baud-rate and clock-out frequencies can not be determined independently from one another since they both use RCAP2H and RCAP2L Jan Waclawek [EDIT]PS. I discovered why I did not find the clockout description: I was doing a search for T2OE, while in the clockout section, they mistyped the bit name for T20E... [EDIT2] It is interesting to see that this typo is present in probably all Philips '52 veriants datasheet, even in the XAs... It is there in the P89V51RD2 (and also the SST equivalent), but the chapter is placed more logically (but they assume 6-clock mode in the description while not mentioning this fact, this is very confusing). |
