Clear Status Register
The Clear Status Register command clears the status register. It functions independent
of VPP. The WSM sets and clears SR[7,6,2], but it sets bits SR[5:3,1] without clearing
them. The Status Register should be cleared before starting a command sequence to
avoid any ambiguity. A device reset also clears the Status Register.
Read Configuration Register
The RCR is used to select the read mode (synchronous or asynchronous), and it defines
the synchronous burst characteristics of the device. To modify RCR settings, use the
Configure Read Configuration Register command (see
Bus Cycles” on page
RCR contents can be examined using the Read Device Identifier command, and then
reading from offset 0x05 (see
The RCR is shown in
