PLLMUL: Configuration of the PLL clock multiplication
PLO: PLL power-on configuration value for PLL use
CLKD: Clock Division Factor. When writing a value of 0 or 1 to CLKD, then the clock frequency is divided by 1
PLB: 1 to bypass PLL

SDx: 1 to shut down module x
I0x: 1 to enable module x recovery on interrupt 0
I1x: 1 to enable module x recovery on interrupt 1
I2x: 1 to enable module x recovery on interrupt 2
IVx: 1 to enable module x recovery on vectored interrupt
T0x: 1 to enable module x recovery on timer 0
T1x: 1 to enable module x recovery on timer 1
NMx: 1 to enable module x recovery on non-maskable interrupt
EXx: 1 to enable module x recovery on external signal
BMx: 1 to enable module x breakpoint mask

The module "x" in registers above means
 - C: core
 - D: DMA
 - S: SIO
 - G: GLUE
 - H: APBP/HPI
 - A: AHBM
 - O: OCEM
 - 0: Timer 0
 - 1: Timer 1
 - J: JAM
 - B: BTDMP 0/1/2/3, for bit 0/1/2/3 respectively
