.0 LSB
Must be initialized to 0FFH.
ROM Address: 003EH
MSB .7 .6 .5 .4 .3 .2 .1 .0 LSB
LVR enable/disable bit:
0 = Disable
1 = Enable
LVR level selection bits:
1 0 = 2.2v
1 1 = 3.0v
0 1 = 3.9v
Not used
ROM Address: 003FH
MSB .7 .6 .5 .4 .3 .2 .1
.0 LSB
Not used.
NOTES:
1. When you use external oscillator, P1.1 must be set to output
port to prevent current consumption.
2. The unused bits in 3EH, 3FH must be initialized to “ 1” .
Oscillator selection bits:
1 1 = External crystal/ceramic oscillator
1 0 = External RC
0 1 = Internal RC (1MHz when VDD = 5 V)
0 0 = Internal RC (8MHz when VDD = 5 V)
