NOTE: s = source d = destination
Computed branches (BR) and subroutine calls (CALL) instructions use the same addressing modes as the other
instructions. These addressing modes provide indirectaddressing, ideally suited for computed branches and
calls. The full use of this programming capability permits a program structure different from conventional 8- and
16-bit controllers. For example, numerous routines can easily be designed to deal with pointers and stacks
instead of using flag type programs for flow control.
operation modes and interrupts
The MSP430 operating modes support various advanced requirements for ultra low power and ultra low energy
consumption. This is achieved by the intelligent management of the operations during the different module
operation modes and CPU states. The requirements are fully supported during interrupt event handling. An
interrupt event awakens the system from each of the various operating modes and returns with the RETI
instruction to the mode that was selected before the interrupt event. The clocks used are ACLK and MCLK.
ACLK is the crystal frequency and MCLK is a multiple of ACLK and is used as the system clock.
The software can configure five operating modes:
Active mode (AM). The CPU is enabled with different combinations of active peripheral modules.
Low power mode 0 (LPM0). The CPU is disabled, peripheral operation continues, ACLK and MCLK signals
are active, and loop control for MCLK is active.
Low power mode 1 (LPM1). The CPU is disabled, peripheral operation continues, ACLK and MCLK signals
are active, and loop control for MCLK is inactive.
Low power mode 2 (LPM2). The CPU is disabled, peripheral operation continues, ACLK signal is active,
and MCLK and loop control for MCLK are inactive.
Low power mode 3 (LPM3). The CPU is disabled, peripheral operation continues, ACLK signal is active,
MCLK and loop control for MCLK are inactive, and the dc generator for the digital controlled oscillator (DCO)
(
MCLK generator) is switched off.
Low power mode 4 (LPM4). The CPU is disabled, peripheral operation continues, ACLK signal is inactive
(crystal oscillator stopped), MCLK and loop control for MCLK are inactive, and the dc generator for the DCO
is switched off.
The special function registers (SFR) include module-enable bits that stop or enable the operation of the specific
peripheral module. All registers of the peripherals may be accessed if the operational function is stopped or
enabled. However, some peripheral current-saving functions are accessed through the state of local register
bits. An example is the enable/disable of the analog voltage generator in the LCD peripheral, which is turned
on or off using one register bit.
