PS2 Clock Generator (PS2CLK)
12.1 Introduction
This module provides the capability to generate PS2 clock.
12.2 Functional Description
Figure 12-1
PS2EN bit. When the module is enabled, the output port becomes an open-drain output. A two phase
clock is created by the prescaler block, one is driving the clock generator unit and the other is driving the
interrupt generator. The clock generator drives the output port directly if CLKEN bit is set, while the
interrupt generator enables CPU interrupt at the different clock phase. The CPU interrupt can be masked
by clearing the PS2IEN bit. The waveform diagram is shown in
When the module is enabled, the output port status is continuous monitored and stored in PSTATUS flag.
