After Reset the CPU has to write a minimum set of registers and an optional set
dependent on the required features and operating modes.
First, the serial mode, the configuration of the serial port and the clock mode have to be
defined via the CCR0 and CCR1 registers. The clock mode must be set before power-up
(CCR1). The CPU may switch the ESCC2 between power-up and power-down mode.
This has no influence upon the contents of the registers, i.e. the internal state remains
stored. In power-down mode however, all internal clocks and the oscillator circuitry are
disabled, no interrupts are forwarded to the CPU (interrupts of universal port excluded).
This state can be used as a standby mode, when the ESCC2 is temporarily not used,
thus substantially reducing power consumption.
The ESCC2 should usually be initialized in power-down mode.
The need for programming further registers depends on the selected features (serial
mode, clock mode specific features, operating mode, address mode, user demands).
Table 6 gives an overview about initialization of the control registers.
