Sector Erase Resume Erase can be resumed after suspend with Addr. (“H†or “Lâ€). Data (30h)
* : The fourth bus cycle is only for read.
Notes: • Address bits A19 to A11 = X = “H†or “L†for all address commands except or Program Address (PA) and
Sector Address (SA)
• Bus operations are defined in “MBM29LV008TA/008BA User Bus Operationsâ€.
• RA = Address of the memory location to be read
IA = Autoselect read address that sets A10, A6, A1, A0.
PA = Address of the memory location to be programmed
Addresses are latched on the falling edge of the write pulse.
SA = Address of the sector to be erased. The combination of A19, A18, A17, A16, A15, A14, and A13 will
uniquely select any sector.
• RD = Data read from location RA during read operation.
ID = Device code / manufacture code for the address located by IA.
PD = Data to be programmed at location PA. Data is latched on the rising edge of write pulse.
• Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
• Command combinations not described in Standard Command Definitions table are illegal.
