DESCRIPTION OF FUNCTIONS
CPU
CPU core:
ARM7TDMI
Operating frequency:
1 MHz to 33 MHz
Instructions:
ARM instruction (32-bit length) and Thumb instruction (16-bit length) can be mixed.
General register bank:
31
× 32 bits
Built-in barrel shifter:
ALU and barrel shift operations can be executed by one instruction.
Multiplier:
32 bits
× 8 bits (Modified Booth’s Algorithm)
Built-in debug function:
JTAG interface, break point register
Built-in Memory
RAM:
8 KB (2K
× 32 bits)
Connected to processor bus (1 cycle access)
Interrupt Controller
Fast interrupt input (FIQ) and interrupt input (IRQ) are employed as interrupt input signals of ARM core. The
interrupt controller controls these interrupt signals going to ARM core.
(1)
Interrupt sources of ML674000
FIQ: 1 source, external source (external pin: EFIQ_N)
IRQ: 22 sources, internal sources : 18, external sources : 4 (external pins: EXINT [3 : 0])
(2)
Interrupt priority level
Priority can be set in 8 levels for each source.
(3)
External interrupt pin input
Level sense: Interrupt signal level is selected.
Edge sense:
Rise or fall is selected.
Timer
7 channels of 16-bit reload timers are employed. Of these, 1 channel is used as system timer for OS.
The timers of other 6 channels are used in application software.
(1)
System timer: 1 channel
16-bit auto reload timer: Used as system timer for OS
(This timer is incorporated in PLAT-7B.)
(2)
Application timer: 6 channels
16-bit auto reload timer
One shot, interval
Clock can be set for each channel
WDT
Possesses the function of interval timer mode in addition to the watch dog timer function.
(1)
16-bit timer
(2)
Watch dog timer or interval timer mode can be selected
(3)
Interrupt reset generation
(4)
Maximum period: 200 msec or longer
PWM
This LSI contains two channels of PWM (Pulse Width Modulation) function which can change the duty in a
certain fixed period. The PWM output resolution is 16 bits for each channel.
