LPREC—Low-Power Recovery
3.9 CLOCK CONTROL REGISTER
The CKCR is a 16-bit register is a memory-mapped read-write register. The address of this
register is fixed at $0FA in supervisor data space (FC = 5). This register controls the state
of CLKO, RCLK1, TCLK1, and BRG1. This register is cleared at reset.
CLKOM—CLKO Mode
TSTCLK1—Three-state TCLK1

After a system reset, this bit defaults to zero.
After a system reset, the bit defaults to zero.
These bits may be written at any time to change the mode of the CLKO pin. Changes to
CLKO are made while the CLKO signal is high. No spikes on CLKO will occur when the
CLKOM bits are changed.
0 = The low-power clock divider input clock is the main clock.
1 = The low-power clock divider input clock is the main clock divided by 16. Thus,
0 = Nondestructive recovery from low power. The processor returns to full frequency
1 = Destructive recovery from low power. The processor returns to full frequency and

cant power savings can be obtained by disabling CLKO. Typical power savings
may range between 2 and 6 mA, depending on the CLKO loading. Disabling
CLKO can also reduce noise and electromagnetic interference on the printed cir-
cuit board.
