PEPROM Registers
PEPRZF — PEPROM Row Zero Flag
This read-only bit is set when the PEPROM bit select register selects
the first row (row zero) of the PEPROM array. Selecting any other row
clears PEPRZF. Monitoring PEPRZF can reduce the code needed to
access one byte of eight PEPROM locations. Reset clears the
PEPROM bit select register, thereby setting the PEPRZF bit by
default.
1 = Row zero selected
0 = Row zero not selected
