2. Must be tied to ground
The differences versus the 8-pin packages are listed below:
The ICC signals (ICCCLK and ICCDATA) are mapped on dedicated pins;
The RESET signal is mapped on a dedicated pin. It is not multiplexed with PA3.
PA3 pin is always configured as output. Any change on multiplexed IO reset control registers
(MUXCR1 and MUXCR2) will have no effect on PA3 functionality. Refer to “Register
description” on page 41.
