FLASH-1 Memory
4.3 FLASH-1 Control and Block Protect Registers
The FLASH-1 array has two registers that control its operation, the FLASH-1 Control Register (FL1CR)
and the FLASH-1 Block Protect Register (FL1BPR).
4.3.1 FLASH-1 Control Register
The FLASH-1 Control Register (FL1CR) controls FLASH-1 program and erase operations.
HVEN — High-Voltage Enable Bit
MASS — Mass Erase Control Bit
ERASE — Erase Control Bit
PGM — Program Control Bit
52
This read/write bit enables the charge pump to drive high voltages for program and erase operations
in the array. HVEN can only be set if either PGM = 1 or ERASE = 1 and the proper sequence for
program or erase is followed.
Setting this read/write bit configures the FLASH-1 array for mass or page erase operation.
This read/write bit configures the memory for erase operation. ERASE is interlocked with the PGM bit
such that both bits cannot be set at the same time.
This read/write bit configures the memory for program operation. PGM is interlocked with the ERASE
bit such that both bits cannot be equal to 1 or set to 1 at the same time.
1 = High voltage enabled to array and charge pump on
0 = High voltage disabled to array and charge pump off
1 = Mass erase operation selected
0 = Page erase operation selected
1 = Erase operation selected
0 = Erase operation unselected
1 = Program operation selected
0 = Program operation unselected
