P2DR
R/W
Port P2 is a 3-bit input/output port.
It is also used as an external interrupt, a STOP mode release signal input, and low-frequency crystal oscillator con-
During reset, the P2DR is initialized to “1”.
A low-frequency crystal oscillator (32.768 kHz) is connected to pins P21 (XTIN) and P22 (XTOUT) in the dual-
It is recommended that pin P20 should be used as an external interrupt input, a STOP mode release signal input, or
P2 port output latch (P2DR) and P2 port terminal input (P2PRD) are located on their respective address.
When read the output latch data, the P2DR should be read and when read the terminal input data, the P2PRD reg-
