The following Table 12 contains the functional description of all C515C-8E pins which
are required for OTP memory programming.

This input must be at static “0” (active) level during the
whole programming mode.

I
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
17
I
Basic programming mode select
This input is used for the basic programming mode
selection and must be switched according Figure 27.
PRD
18
I
Programming mode read strobe
This input is used for read access control for OTP
memory read, version byte read, and lock bit read
operations.
PALE
19
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
whenever the logic level of PMSEL1,0 is changed.
