Voltage Regulator Controller
AT91SAM7X512/256/128 Preliminary
The purpose 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 SLCK
• Programmable 16-bit prescaler for SLCK accuracy compensation
• Two PIO Controllers, each controlling 31 I/O lines
• 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
