2.2 System Clock Controller
2.1.3 Data Memory (RAM)
2.2.1 Clock Generator
The system clock controller consists of a clock generator, a timing generator, and a standby controller.
(0040H to 00FFH) of the internal RAM are located in the direct area; instructions with shorten operations are
available against such an area.
should be initialized by an initialization routine.
and peripheral hardware. It contains two oscillation circuits: One for the high-frequency clock and one for the
low-frequency clock. Power consumption can be reduced by switching of the standby controller to low-power
operation based on the low-frequency clock.
between the XIN/XOUT and XTIN/XTOUT pins respectively. Clock input from an external oscillator is also
possible. In this case, external clock is applied to XIN/XTIN pin with XOUT/XTOUT pin not connected.
The TMP86CH12MG has 512bytes (Address 0040H to 023FH) of internal RAM. The first 192 bytes
The data memory contents become unstable when the power supply is turned on; therefore, the data memory
The clock generator generates the basic clock which provides the system clocks supplied to the CPU core
The high-frequency (fc) clock and low-frequency (fs) clock can easily be obtained by connecting a resonator
