This input must be at static “1“ (active) level during the whole
programming mode.

Programming mode selection pins
These pins are used to select the different access modes in
programming mode. PMSEL1,0 must satisfy a setup time to the
rising edge of PALE. When the logic level of PMSEL1,0 is
changed, PALE must be at low level.
PSEL
8I
Basic programming mode select
This input is used for the basic programming mode selection
and must be switched according Figure 28.
PRD
9I
Programming mode read strobe
This input is used for read access control for OTP memory read,
Version Register read, and lock bit read operations.
PALE
10
I
Programming address latch enable
PALE is used to latch the high address lines. The high address
lines must satisfy a setup and hold time to/from the falling edge
of PALE. PALE must be at low level when the logic level of
PMSEL1,0 is changed.
