• Manufacturer: ETC-unknow

STATUS REGISTER
X2UP:Sub-crystal oscillator warm-up status. When set, this bit indicates the crystal oscillator has
HIP: High Priority Interrupt Status. When set, it indicates that software is servicing a high priority
LIP: Low Priority Interrupt Status. When set, it indicates that software is servicing a low priority
X1UP:Crystal Oscillator Warm-up Status. When set, this bit indicates the crystal oscillator has
※
(CKCON1.0 = “1”, M/S) & disable X1 OSC (PMR.3 = “1”, X1OFF).
FSK TRANSIMT CONTROL REGISTER
FTE: FSK transmit Enable; Enable:1, Disable=0
FTM: FSK signal Standard; Bellcore:1, V.23=0
FDS: FSK data sending status
LO0, LO1: FSK transmit level option
Please insert at least 10 instructions NOP after X2UP = ”1”, then switch Fsys = Fs
interrupt. This bit will be cleared when the program executes the corresponding RETI instruction.
interrupt. This bit will be cleared when the program executes the corresponding RETI instruction.
Bit:
completed the warm-up delay. When X2OFF bit is set, hardware will clear this bit. There are two
options which are selected by option code for warm-up delay, one is 1024 clocks warm-up
delay, other is 65536 clocks warm-up delay.
completed the 65536 clocks warm-up delay. Each time the crystal oscillator is restarted by exit
from power down mode or the X1OFF bit is set, hardware will clear this bit. This bit is set to 1
after a power-on reset. When this bit is cleared, it prevents software from setting the XT/ RG bit
to enable CPU operation from crystal oscillator. There are two options which is selected by
option code for warm-up delay, one is 4096 clocks warm-up delay, other is 65536 clocks warm-
up delay.
