7. System Controller
6438F–ATARM–21-Jun-10
A[25:0], controlled by 4 registers, DELAY5, DELAY6, DELAY7and DELAY8, located in the
HSMC3 user interface
A25 on PC[12] and A[24:19] on PC[7:2]
The delay can only be inserted on the HSMCI0 and HSMCI1 I/O lines, so on PA[9:2] and
PA[30:23]. The delay is controlled by 2 registers, DELAY1 and DELAY2, located in the PIOA
user interface.
The System Controller is a set of peripherals that allows handling of key elements of the system,
such as power, resets, clocks, time, interrupts, watchdog, etc.
