DS_1210F_001
The master clock control register enables different sections of the clock circuitry and specifies the value
of the VCO Mcount divider. The MCLK must be configured to operate at 96MHz to ensure proper
operation of some of the peripheral blocks according to the following formula:
Mcount is configured in the MCLKCtl register must be bound between a value of 1 to 10. The possible
crystal or external clock frequencies for getting MCLK = 96MHz are shown in Table 11.
Master Clock Control Register (MCLKCtl): 0x8F 0x0A
The MPU clock that drives the CPU core defaults to 3.6923MHz after reset. The MPU clock is scalable
by configuring the MPU Clock Control register.

High-speed oscillator disable. When set = 1, disables the high-speed
crystal oscillator and VCO/PLL system. Do not set this bit = 1.
1 = Disable the keypad logic clock.
1 = Disable the smart card logic clock.
This value determines the ratio of the VCO frequency (MCLK) to the
high-speed crystal oscillator frequency such that:
MCLK = (MCount*2 + 4)* F
that MCLK = (2*2 + 4)*12.00MHz = 96MHz.
MCLK = (Mcount * 2 + 4) * F
