low-power and IDLE modes
The TMS370Cx36 devices have two low-power modes (STANDBY and HALT) and an IDLE mode. For
mask-ROM devices, low-power modes can be disabled permanently through a programmable contact when
the mask is manufactured.
The STANDBY and HALT low-power modes significantly reduce power consumption by reducing or stopping
the activity of the various on-chip peripherals when processing is not required. Each of the low-power modes
is entered by executing the IDLE instruction when the PWRDWN/IDLE bit in SCCR2 has been set to 1. The
HALT/STANDBY bit in SCCR2 controls the low-power mode selection.
In the STANDBY mode (HALT/STANDBY = 0), all CPU activity and most peripheral module activity is stopped;
however, the oscillator, internal clocks, the PACT counter, and the first PACT command entry remain active in
all modules. System processing is suspended until a qualified interrupt (hardware RESET or external interrupt
on INT1) is detected.
In the HALT mode (HALT/STANDBY = 1), the TMS370Cx36 is placed in its lowest power consumption mode.
The oscillator and internal clocks are stopped, causing all internal activity to be halted. System activity is
suspended until a qualified interrupt (hardware RESET or external interrupt on the INT1) is detected. The
power-down mode-selection bits are summarized in Table 9.
