GENERAL DESCRIPTION
A default serial loader program in the Boot ROM allows In-System Programming (ISP) of the Flash memory without the need for a loader in the Flash code. User programs may erase and reprogram the Flash memory at will through the use of standard routines contained in the Boot ROM (In-Application Programming).● Boot ROM contains low level Flash programming routines for In-Application Programming and a default serial loader using the UART
● 1024 bytes of on-chip data RAM
● Supports off-chip program and data addressing up to 1 megabyte (20 address lines)
● Three standard counter/timers with enhanced features (same as XA-G3 T0, T1, and T2). All timers have a toggle output capability
● Watchdog timer
● Two enhanced UARTs with independent baud rates
● Seven software interrupts
● Four 8-bit I/O ports, with 4 programmable output configurations for each pin
FEATURES
● 32 kbytes of on-chip Flash program memory with In-System Programming capability● Three Flash blocks = two 8 k...
