While in i/o mode, keyboard joystick types (Sinclair, Cursor, etc) produce no readings but the current state of pins can still be read via the Kempston ports. When leaving i/o mode, joystick operation resumes after ~64 scan lines have passed.<br /> <br /> * CTC channel 3 is currently used to drive pin 7 in clock mode. Freq = Fctc3 / 2.<br /> ** CTS_n is only active if the seleced uart is in hw flow control mode.</div>
