Can the RDY signal be used under register conditions?
Latest Updated:03/15/2012
Question:
The manual says "To use the RDY signal, set the corresponding CS3W to CS0W bit to "0" (with wait state).", but can the RDY signal be used under the following register conditions?:
- PM17 bit of the PM1 Register is "0" (no-wait)
- CSi bit (i=0 to 3) of the CSR Register is "1" (chip select output enabled) and CSiW bit is "0" (with wait)
- PM17 bit of the PM1 Register is "0" (no-wait)
- CSi bit (i=0 to 3) of the CSR Register is "1" (chip select output enabled) and CSiW bit is "0" (with wait)
Answer:
Yes, the RDY signal can be used in the CSi area where a wait is set by setting CSiW bit to "0". PM17 bit sets a wait to the internal ROM and RAM.
