04 Display Device Data or Blank Check – Record type 04 causes the contents of the entire Flash array to be sent out
the serial port in a formatted display. This display consists of an address and the contents of 16 bytes starting with that
address. No display of the device contents will occur if security bit 2 has been programmed. Data to the serial port is
initiated by the reception of any character and terminated by the reception of any character.

In Application Programming Method
Several In Application Programming (IAP) calls are available for use by
an application program to permit selective erasing and programming of
Flash sectors. All calls are made through a common interface,
PGM_MTP. The programming functions are selected by setting up
the microcontroller’s registers before making a call to PGM_MTP at
FFF0H. The oscillator frequency is an integer number rounded down
to the nearest megahertz. For example, set R0 to 11 for 11.0592 MHz.
Results are returned in the registers. The IAP calls are shown in
Table 10.
Using the Watchdog Timer (WDT)
The P89C51Rx2 devices support the use of the WDT in IAP. The
user specifies that the WDT is to be fed by setting the most
significant bit of the function parameter passed in R1 prior to calling
PGM_MTP. The WDT function is only supported for Block Erase
when using Quick Block Erase. The Quick Block Erase is specified
by performing a Block Erase with register R0 = 0. Requesting a
WDT feed during IAP should only be performed in applications that
use the WDT since the process of feeding the WDT will start the
WDT if the WDT was not running.
