KPINT
This bit indicates the Keypad logic has set Key_Detect bit and a key
location may be read. Cleared on read of register.
1.7.12 Emulator Port
The emulator port, consisting of the pins E_RST, E_TCLK and E_RXTX, provides control of the MPU
through an external in-circuit emulator. The E_TBUS[3:0] pins, together with the E_ISYNC/BRKRQ, add
trace capability to the emulator. The emulator port is compatible with the ADM51 emulators
manufactured by Signum Systems.
If code trace capability is needed on this interface, 20pF capacitors (to ground) need to be added to allow
the trace function capability to run properly. These capacitors should be attached to the TBUS0:3 and
ISBR signals.
