♦
Clock supply
The clock is supplied from the internal crystal oscillator of the IE-784026-R-EM1 and target system.
♦
Memory
• Alternate memory capacity
Internal ROM and alternate memory: 1M bytes (0 wait, except SFR internal RAM)
• Mapping units
Peripheral RAM : 32K bytes MAX.
Internal ROM : 8K-byte units
Alternate memory : 4K-byte units
Peripheral RAM : 256-byte units
♦
Event detection
• Bus event detection condition : Detects data read/write or program fetch operation. Can be set
by mask data (address/data/status/external data signal).
• Program execution detection condition : Detects program execution at any address. Four points can be
set (address/external data signal).
• External data detection condition : Detects that external sense clips 1 through 4 have reached
predetermined levels.
Can be set by mask data.
• External trigger output : High-level signal is output from TRGOUT pin when external
trigger condition is satisfied.
