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 EEADR) and a data latch
(EEDATA). Data EEPROM is read by loading EEADR
with the desired memory location and initiating a
memory
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 (see Figure 5-4).
The command sequence to read a single byte of data
is shown in Table 5-2.

Step 1: Direct access to data EEPROM.
Step 2: Set the data EEPROM Address Pointer.
Step 3: Initiate a memory read.
Step 4: Load data into the Serial Data Holding register.
