Write Program Memory (0AH)
to Program Memory. This command is equivalent to the LDC and LDCI instructions.
Data can be written 1-65536 bytes at a time (65536 bytes can be written by setting size
to zero). The on-chip Flash Controller must be written to and unlocked for the
programming operation to occur. If the Flash Controller is not unlocked, the data is
discarded. If the device is not in DEBUG mode or if the Read Protect Option Bit is
enabled, the data is discarded.
Read Program Memory (0BH)
from Program Memory. This command is equivalent to the LDC and LDCI
instructions. Data can be read 1-65536 bytes at a time (65536 bytes can be read by
setting size to zero). If the device is not in DEBUG mode or if the Read Protect Option
Bit is enabled, this command returns
(Flash version only) Write Data Memory (0CH)
command writes data to Data Memory. This command is equivalent to the LDE and
LDEI instructions. Data can be written 1-65536 bytes at a time (65536 bytes can be
written by setting size to 0). If the device is not in DEBUG mode or if the Read
Protect Option Bit is enabled, the data is discarded.
Read Data Memory (0DH)
Memory. This command is equivalent to the LDE and LDEI instructions. Data can be
read 1-65536 bytes at a time (65536 bytes can be read by setting size to 0). If the
device is not in DEBUG mode, this command returns
