10.9.7 Register Description
The JBLPD peripheral uses 48 registers that are
mapped in a single page of the ST9 register file.
Twelve registers are mapped from R240 (F0h) to
R251 (FBh): these registers are usually used to
control the JBLPD. See
Stacked Registers
these registers.
Thirty-six registers are mapped from R252 (FCh)
to R255 (FFh). This is obtained by creating 9 sub-
pages, each containing 4 registers, mapped in the
same register addresses; 4 bits (RSEL[3:0]) of a
