RTC_DEC_SEC
RTC_INC_SEC
201C[1]
201C[0]
0
W
RTC time correction bits. Only one bit may be pulsed at a time.
When pulsed, causes the RTC time value to be incremented (or
decremented) by an additional second the next time the RTC_SEC
register is clocked. The pulse width may be any value. If an
additional correction is desired, the MPU must wait 2 seconds
before pulsing one of the bits again. Each write to one of these bits
must be preceded by a write to 201F (WE).
RTM_E
2002[3]
0
R/W
Real Time Monitor enable. When ‘0’, the RTM output is low. This
bit enables the two wire version of RTM
RTM0[7:0]
RTM1[7:0]
RTM2[7:0]
RTM3[7:0]
2060
2061
2062
2063
0
R/W
Four RTM probes. Before each CE code pass, the values of these
registers are serially output on the RTM pin. The RTM registers are
ignored when RTM_E=0.
SECURE
SFRB2[6]
0
--
R/W
Enables security provisions that prevent external reading of flash
memory and CE program RAM. This bit is reset on chip reset and
may only be set. Attempts to write zero are ignored.
SLEEP
20A9[6]
0
W
Takes the 6521DE/FE to sleep mode. Ignored if system power is
present. The part will wake when the autowake timer times out,
when push button is pushed, or when system power returns.
SUM_CYCLES[5:0]
2001[5:0]
0
R/W
The number of pre-summer outputs summed in the final summer.
TMUX[4:0]
20AA[4:0]
2
--
R/W
Selects one of 32 signals for TMUXOUT.
