C8051F326/7
10.2. Internal Low-Frequency (L-F) Oscillator
C8051F326/7 devices include a low-frequency oscillator. The OSCLCN register (see SFR Definition 10.3)
is used to enabled the oscillator.
10.3. CMOS External Clock Input
A CMOS clock can be used as an external clock input. The CMOS clock should be wired to the XTAL2 pin
(P0.3) as shown in Figure 10.1 on Page 71. Port pins must be configured when using the external oscilla-
tor circuit. The Port I/O Crossbar should be configured to allow digital inputs be setting INPUTEN (GPI-
OCN.6). Also, P0.3 should be configured to open drain mode. See Section “11. Port Input/Output” on
page 79 for more information.
