TABLE B-4: TABLE B-4 EXECUTIVE (EXEC) WORD ADDRESSES
S
tate Controller – The Executive state controller manages background functions. The
host enacts a function by writing to EXEC_STATE with a valid “state entry value” (i.e.,
0x80-0x87). Writing values outside this range will cause unknown results.
TABLE B-5: EXEC STATE ENTRY VALUES
REG NAME DESCRIPTION
0x00 EXEC_STATE State of executive state controller
bit 7 == 1: force state controller to one of eight “entry
points” specified by bits[2:0]
0x01 EXEC_ADC_CH0 ADC results of CHANNEL AN0 (potentiometer RP1)
0x02 EXEC_RTC_SE binary value representation of RTC “SECONDS”
0x03 EXEC_STATUS state of communications connector pins:
bit 0: PIN 1 (AUX1)
bit 1: PIN 4 (SDA)
bit 2: PIN 5 (SCL)
bit 3: PIN 6 (AUX2)
bits[5:4]: undefined
bit 6: operation error
bit 7: operation busy
0x04 EXEC_04 undefined (can be read/written with no operational effect)
0x05 EXEC_05 undefined (can be read/written with no operational effect)
0x06 EXEC_06 undefined (can be read/written with no operational effect)
