IME flag (master enable flag)
The IME enables or disables all interrupts at the
same time. The IE command, when executed, sets
the IME flag and enables the interrupt specified by
the mask flag setting. The ID command resets the
IME flag, disabling process of any interrupt request.
Setting the IME flag to reset after releasing
hardware reset, all interrupts are inhibited.
Mode register RE (interrupt mask flag)
The mode register RE (RE0, RE1 and RE2;
interrupt mask flag) individually enables or disables
three type of interrupts.
Timer/Counter
The SM5K3/5K4/5K5 have a pair of built-in
timer/counter. The timer/counter are used to handle
periodic interrupts and to count. The overflowing
timer can be used to disable the halt mode. The
timer/counter serve as interval timer.
The timer/counter consists of an 8-bit count register
RA, modulo register RB (for counter initial value
setting), 15-bit divider and 4-bit mode register RC
(for count clock selection). The configuration of the
timer/counter is shown in Fig. 10.
