getch
The getch function is a ZILOG function that waits for the next character to appear at the
serial port and returns its value. This function does not wait for end-of-line to return as
getchar does. getch does not echo the character received.
Synopsis
#include

int getch(void) ;
Returns
The next character that is received at the selected UART.
Example
#include

int val;

void main()

{

init_uart(_UART0,_DEFFREQ,_DEFBAUD);

val = getch(); // Get character from _UART0

}
Before using this function, the init_uart() function must be called to initialize and
select the UART. The default UART is _UART0.
INIT_FLASH
The INIT_FLASH function is a Zilog function that sets the target clock frequency for
Flash write. The following target clock frequencies are predefined in
eZ8.h for conve-
nience:
FREQ20000 /* for 20 MHz */
FREQ18432 /* for 18.432 MHz */
FREQ16000 /* for 16 MHz */
FREQ14000 /* for 14 MHz */
FREQ12000 /* for 12 MHz */
FREQ08000 /* for 8 MHz */
FREQ04000 /* for 4 MHz */
