Real-time Timer
PIO Controller
Voltage Regulator Controller
The aim of this controller is to select the Power Mode of the Voltage Regulator between Normal Mode (bit 0 is cleared) or
Standby Mode (bit 0 is set).
32-bit free-running counter with alarm running on prescaled SCLK
Programmable 16-bit prescaler for SLCK accuracy compensation
One PIO Controller, controlling 32 I/O lines (21 for SAM7S32/16)
Fully programmable through set/clear registers
Multiplexing of two peripheral functions per I/O line
For each I/O line (whether assigned to a peripheral or used as general-purpose I/O)
Synchronous output, provides Set and Clear of several I/O lines in a single write
Input change interrupt
Half a clock period glitch filter
Multi-drive option enables driving in open drain
Programmable pull-up on each I/O line
Pin data status register, supplies visibility of the level on the pin at any time
