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 15.

Using the Watchdog Timer (WDT)

The 89C66x 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 the

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 working.

Table 15. IAP calls

; 4000h = block 2

; 8000h = block 3

; C000h = block 4
