Access:
Possible limitations on PLLA input frequencies and multiplier factors should be checked before using the PMC.
Warning: Bit 29 must always be set to 1 when programming the CKGR_PLLAR register.
This register can only be written if the WPEN bit is cleared in
• DIVA: Divider
• PLLACOUNT: PLLA Counter
Specifies the number of Slow Clock cycles x8 before the LOCKA bit is set in PMC_SR after CKGR_PLLAR is written.
• MULA: PLLA Multiplier
0 = The PLLA is deactivated.
1 up to 2047 = The PLLA Clock frequency is the PLLA input frequency multiplied by MULA + 1.
