5.3
A Configuration address may be read and output on
PGD via the 4-bit command, ‘1001’. Configuration data
is read and written in a byte-wise fashion, so it is not
necessary to merge two bytes into a word prior to a
compare. The result may then be immediately
compared to the appropriate Configuration data in the
programmer’s memory for verification. Refer to
Section 5.1 “Read Program Flash, ID Locations and
Configuration Bits” for implementation details of
reading Configuration data.
5.4
Data EEPROM is accessed one byte at a time via an
Address Pointer (register pair EEADRH:EEADR) and a
data latch (EEDATA). Data EEPROM is read by
loading EEADRH: EEADR with the desired memory
location and initiating a memory read by appropriately
configuring the EECON1 register. The data will be
loaded into EEDATA, where it may be serially output on
PGD via the 4-bit command, ‘0010’ (Shift Out Data
Holding register). A delay of P6 must be introduced
after the falling edge of the 8th PGC of the operand to
allow PGD to transition from an input to an output.
During this time, PGC must be held low, as shown in
Figure 5-4.
The command sequence to read a single byte of data
is shown in Table 5-2.
