For chips where getenv("FLASH_ERASE_SIZE") > getenv("FLASH_WRITE_SIZE")
WRITE_PROGRAM_EEPROM -
Writes 2 bytes,does not erase (use ERASE_PROGRAM_EEPR
WRITE_PROGRAM_MEMORY -
Writes any number of bytes,will erase a block whenever the first
(lowest) byte in a block is written to. If the first address is not th
start of a block that block is not erased.
ERASE_PROGRAM_EEPROM -
Will erase a block. The lowest address bits are not used.
For chips where getenv("FLASH_ERASE_SIZE") = getenv("FLASH_WRITE_SIZE")
WRITE_PROGRAM_EEPROM -
Writes 2 bytes, no erase is needed.
WRITE_PROGRAM_MEMORY -
Writes any number of bytes, bytes outside the range of the write
block are not changed. No erase is needed.
ERASE_PROGRAM_EEPROM -
Not available.
PSP
These options let to configure and use the Parallel Slave Port on the supported devices.
Relevant Functions:
setup_psp(mode)
psp_output_full()
psp_input_full()
psp_overflow()
Enables/disables the psp port on the chip
Returns 1 if the output buffer is full(waiting to be read by the
external bus)
Returns 1 if the input buffer is full(waiting to read by the cpu)
Returns 1 if a write occurred before the previously written byte
was read
