Preliminary
For the HT95C200/20P, the PD0~PD7 and
COM0~COM7 share the same pads. They can only be
selected per byte by software option at any time.
When the PD0~PD7 or the PE0~PE3 are not selected,
the I/O port control register (19H), PEC (1BH) could be
read/write-able and be used as a general user RAM, but
this function is not available for register PD (18H) and
PE (1AH).
FSK decoder
The FSK decoder supports three interrupt sources to
the peripheral interrupt vector. There are ring detect or
line reversal detect, FSK carrier detect and FSK packet
data. Write 0 to the control flag, RMSK, CMSK and
FMSK will enable these interrupt. When any of these in-
terrupt occurs, its interrupt flag (RDETF, CDETF, FSKF)
will be set to 1 by hardware even if the interrupt is dis-
abled. These interrupts will cause a peripheral interrupt
if the peripheral interrupt is enabled.When the periph-
eral interrupt occurs, the interrupt request flag PERF will
be set and a subroutine call to location 10H will occur.
Returning from the interrupt subroutine, the interrupt
flag RDETF, CDETF or FSKF will not be cleared by
hardware, the user should clear it by software. If inter-
rupt flag RDETF is not cleared, next ring detect interrupt
will be inhibited, other interrupt flags CDETF, FSKF
have the same behavior. The power down mode
(F_PWDN=1) will terminate all the FSK decoder func-
tion, however, the registers FSKC, FSKS and FSKD are
accessible at this power down mode.
