Data EEPROM is accessed one byte at a time via an
Address Pointer, EEADR, and a Data Latch, EEDATA.
Data EEPROM is read by loading 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 (see
Figure 4-2).
The command sequence to read a single byte of data
is shown in Table 4-1.

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.
