(DCCON1)
The DCCON1 special function register is used to adjust the exact voltage levels of the on-chip DC/DC converter.

INSTRUCTION SET
The PBB family uses a powerful instruction set which permits the expansion of on-chip CPU peripherals and optimizes
power consumption in Idle and active modes as well as byte efficiency and execution speed. Typical execution times and
energy consumption at a V
DD
of 2.2 V are given in Table 60.
Attention
: for most opcodes the numbers for execution
speed and energy are also strongly dependant on the data (ADD, SUBB, DEC, INC, MUL, DIV, DA, conditional jumps
etc.) and the operand address (CPU internal SFRs or SFRs in a peripheral block).

Adjustment for band gap voltage
; used to trim the band gap voltage [00] = 1.260 V,
[01] = 1.233 V, [10] = 1.286 V, [11] = 1.312 V.
Adjustment for DC/DC converter output voltage in standby mode;
[00] = 1.9 V,
[01] = 2.0 V, [10] = 2.1 V, [11] = 2.2 V.
