18.3 Description of Operation
18.3.1
18.3.2
For each pin of Port 2, any one of high-impedance output mode, P-channel open drain output mode, N-channel open
drain output mode, and CMOS output mode can be selected by setting the Port 2 control registers 0 and 1 (P2CON0
and P2CON1). At a system reset, high-impedance output mode is selected as the initial state.
Depending of the value set in the Port 2 data register (P2D), a “L” level or “H” level signal is output to each pin of Port
2.
Low-speed clock (LSCLK) output, High-speed output clock (OUTCLK) output, melody 0 (MD0) output, or PWM2
(PWM2) output is assigned to Port 2 as a secondary and tertiary function. These pins can be used in a secondary or
tertiary function mode by setting the P22MD to P20MD bits and the P22MD1 to P20MD1 bits of the Port 2 mode
registers (P2MOD, P2MOD1).
The frequency of a low-speed clock (LSCLK) output can be set up by the OCK0 bit and the OCK1 bit of the Port2
mode register 2 (P2MOD2).
