General Description
Chapter 1, Pin Description
Deep sleep drawing “5uA” of current changed to
“3uA”
Application Note added: “The SPI_CS# pin should
be grounded when SMBus, I2C, or BC-Link
communications are used.”
Pin description table updated: Added to pin
function description for RESET pin: “This pin
contains an internal 50uA pull-down current.”
