Address lines
P2.0-7 are used as multiplexed address input lines
A0-A7 and A8-A12. A8-A12 must be latched with
PALE. Address A12 is requred only for the C541U.

Program store enable
This input must be at static “0“ level during the whole
programming mode.

I
Programming mode write strobe
This input is used in programming mode as a write
strobe for OTP memory program and lock bit write
operations During basic programming mode selection
a low level must be applied to PROG.

I
External Access / Programming voltage
This pin must be at 11.5 V (V
PP
) voltage level during
programming of an OTP memory byte or lock bit.
During an OTP memory read operation this pin must
be at high level (V
IH
). This pin is also used for basic
programming mode selection. At basic programming
mode selection a low level must be applied to EA/V
PP
.
Data lines 0-7
During programming mode, data bytes are read or
written from or to the C540U/C541U via the
bidirectional D0-7 lines which are located at port 0.
