Symbol Description
TEST1
TEST1 = 0; normal mode.
TEST1 = 1; EXT_CLK test mode; see
Section 8.7
.
STOP
STOP = 0; RTC source clock runs.
STOP = 1; all RTC divider chain flip-flops are asynchronously set
to logic 0; the RTC clock is stopped (CLKOUT at 32.768 kHz is still
available).
TESTC
TESTC = 0; power-on reset override facility is disabled (set to logic 0
for normal operation).
TESTC = 1; power-on reset override is enabled.
6, 4, 2 to 0 0
By default set to logic 0.
