Clock-Generating Circuit
fAD
This clock has the same frequency as the main clock and is used for A-D conversion.
fUSB
This is the 48mHz clock that is used for USB operation. This clock is generated from the main clock
by the frequency synthesizer circuit.
1.2.6.3 Clock Output
In single-chip mode, the clock output function select bits (bits 0 and 1 at address 000616) enable f8 or
f32 to be output from the P37/CLKOUT pin. When the WAIT peripheral function clock stop bit (bit 2 at
address 000616) is set to “1”, the output of f8 and f32 stops when a WAIT instruction is executed.
Figure 1.13 shows the system clock control registers 0 and 1.

Note 1: Set bit 0 of the Protect register (address 000A16) to "1" before writing to this register.
Note 2: Changes to "1" when shifting to stop mode.
Note 3: Can be selected when bit 6 of the System clock control register 0 (address 000616) is "0".
If "1", division mode is fiixed at "8".
Note 1: Set bit 0 of the Protect register (address 000A16) to "1" before writing to this register.
Note 2: Changes to "1" when shifting to stop mode.
