3.3.2

Prescaler Clock Controller

The 9-bit prescaler provides a clock to 8-bit Timer 0, 1, 2, 3, 16-bit Timer 4, 5, and serial

interface 0, 1.

The clock input to the 9-bit prescaler is selected either fFPH or fc/16 by

SYSCR0<PRCK1:0> register.

<PRCK1:0> register is initialized to “00” by resetting.

When the IDLE1 mode (Operates only oscillator) is used, set TRUN<PRRUN> to “0” to

reduce the power consumption of 9-bit prescaler before “HALT” instruction is executed.

3.3.3

Internal Clock Pin Output Function

CLK pin outputs fSYS divided by 2 internal clocks.

Outputs are specified by the clock output control register CKOCR<CLKEN>. Writing “1”

sets clock output, and writing “0” sets high impedance.

During reset, CLK pin is internally pulled up regardless of the value of <CLKEN>

Note: To set <CLKEN> = “0” and set CLK pin to high impedance, pull up externally to prevent

through current which follows to the input buffer of CLK pin.
