(SYSCLK Low Time)
with the CPU executing a mix of instructions in two loops: djnz R1, $, followed by a loop that accesses an
SFR, and moves data around using the CPU (between accumulator and b-register). The supply current will
vary slightly based on the physical location of this code in flash. As described in the Flash Memory chapter, it
is best to align the jump addresses with a flash word address (byte location /4), to minimize flash accesses
and power consumption.
