First cycle of a 2-cycle command; prepares the CUI for block lock
configuration changes. If the next command is not Block Lock (0x01), Block
Unlock (0xD0), or Block Lock-Down (0x2F), the CUI sets SR [5,4], indicating
a command sequence error.
If the previous command was Block Lock Setup (0x60), the addressed block
is locked.
If the previous command was Block Lock Setup (0x60), the addressed block
is unlocked. If the addressed block is in a lock-down state, the operation has
no effect.
If the previous command was Block Lock Setup (0x60), the addressed block
is locked down.
First cycle of a 2-cycle command; prepares the device for a Protection
Register or Lock Register program operation. The second cycle latches the
register address and data, and starts the programming algorithm.
First cycle of a 2-cycle command; prepares the CUI for device read
configuration. If the Set Read Configuration Register command (0x03) is not
the next command, the CUI sets Status Register bits SR[5,4], indicating a
command sequence error.
If the previous command was Read Configuration Register Setup (0x60), the
CUI latches the address and writes A[15:0] (QUAD+) or A[16:1] (EASY BGA/
TSOP) to the Read Configuration Register. Following a Configure RCR
command, subsequent read operations access array data.
