Section 20 Flash Memory
20.3
Register Descriptions
The registers/parameters which control flash memory are shown as follows. To access registers
other than RAMER that control flash memory, set the FLSHE bit in SYSCR2 to 1 in mode which
makes flash memory valid. When FLSHE is 1, some TPU control registers (H'FFFE80 to
H'FFFEB1) cannot be accessed. The FLSHE bit should be cleared before the TPU registers are
accessed.
• Flash code control status register (FCCS)
• Flash program code select register (FPCS)
• Flash erase code select register (FECS)
• Flash key code register (FKEY)
• Flash MAT select register (FMATS)
• Flash transfer destination address register (FTDAR)
• System control register 2 (SYSCR2)
• Flash pass and fail result (FPFR)
• Download pass and fail result (DPFR)
• Flash multipurpose address area (FMPAR)
• Flash multipurpose data destination area (FMPDR)
• Flash erase Block select (FEBS)
• Flash program and erase frequency control (FPEFEQ)
• Flash user branch address set parameter (FUBRA)
• RAM emulation register (RAMER)
• Flash vector address control register (FVACR)
• Flash vector address data register R (FVADRR)
• Flash vector address data register E (FVADRE)
• Flash vector address data register H (FVADRH)
• Flash vector address data register L (FVADRL)
There are several operating modes for accessing flash memory, for example, read mode/program
mode.
There are two memory MATs: user MAT and user boot MAT. The dedicated registers/parameters
are allocated for each operating mode and MAT selection. The correspondence of operating modes
and registers/parameters for use is shown in table 20.4.
